    Email Transfer

    The script is working great for me with one exception--it creates email accounts but only will transfer the emails/mail files when the user name matches the account name (which is a rare case for me). Source accounts use maildir. I don't see any errors/warnings except for the warning for merging the user when it matches the account name.

    Any idea why they aren't copying? I can copy the mail data manually afterward, but it would be nice to not have to do that.

    test

    Hello,

    I have installed Let's Encrypt for my domain (domain.com, mail.domain.com and www.domain.com)

    The certificate matches for both domain.com and www.domain.com. But I get hostname error for mail.domain.com

    "None of the common names in the certificate match the name that was entered ". I have tried creating the subdomain mail.domain, but the issue still does not getting fixed"

    Could you please suggest any methods for securing mail.domain.com using Let's Encrypt cert

    I have imported the cPanel account but when I check emails, the password change option is not visible and it redirects to user account password change instead of specific email.

    I converted 700+ accounts last week with migration script. I would like to leave feedback here about what happened.

    - All websites moved with rsync and then restored with DirectAdmin. I was thinking that I had enough space on my SSD drive. But it seems you need to have double space of what you are moving. Because it converts tar.gz files and create DA backup files after it. So when you move 1GB cpanel backup file, it becomes 2GB backup file in total. So everyone should be aware of that, otherwise you will wait for a long time and see that "not enough space error".

    - My solution was rsync backup folders as part1, part2, part3. So disk space was not a problem anymore.

    - Out of 700 websites, some of them had e-mail password issues. It is fixed by resetting their mail password.

    - Some websites had 22 character mysql database name. So I needed to fix them manually by phpmyadmin and their wp-config files.

    - Some websites are converted without some MySQL tables because of row sizes. It was same MySQL version on both servers. But some of them didn't want to work on DA. I solve that by changing SQL Row as compressed in cPanel and upload them manually to DirectAdmin. It happened on at least 10 websites I converted.

    - With cPanel, many users had ea-72 path entries in their .htaccess files. That websites are showing 403 error when you try to open. When my clients reports this, I manually remove that entry from their .htaccess files and problem solved. So you need to check that if some websites are having errors.

    - My biggest issue is with subdomains. Almost none of them was uploaded to directadmin server. It was in backup file, but many of them were not in the folder after extracted. So when client report it, I download their subdomain folder from cPanel backup and extract it to directadmin manually. This is the biggest issue, because files are lost in convert process. I was using migration script 0.28. So maybe it is fixed in new versions.

    So my struggle is still with subdomains which I need to download and upload manually. Other than that, everything works without a problem.

    I would like to thank DA Staff for making this migration process easier for all.

    I tried again today (after adding some additional logging to the cpanel_to_da script), and it worked, so I'm not sure why it wasn't transferring them before.

    Code:
    tar: homedir/public_html/billings/.htaccess: Cannot open: Not a directory
    tar: homedir/public_html/.htaccess: Cannot open: Not a directory
    I always seem to end up with this error while restoring. Anything I can do except renaming the .htaccess to htaccess at backup time & doing the opposite while restoring?

    I have noticed when people have a catch-all email in Cpanel it will be not migrated to the DirectAdmin server.

    Restoration via command line

    Hi

    any of you know any option to restore accounts via command line so that we can automate things ?

    for user in `ls /var/cpanel/users/`; do { /scripts/pkgacct ${user} /home/all_backups; rsync -avt /home/all_backups/cpmove-${user}.tar.gz root@your_directadmin_server.com:/ho...${user}.tar.gz; rm -f /home/all_backups/cpmove-${user}.tar.gz ; }; done


    I have servers with large amount of accounts and old server is not having enough space and also new server as well cant hold all backups. So I want to fiinsh things one by one and accounts in each of the cpanel servers are like 1000 or some is having more.

    Thanks so much for creating this guide. I'm wondering if anyone has solved this problem creatively:

    Full cPanel backups take time. In fact, a low capacity server of mine takes 24h to complete the backups. In that time many things can change on the source server, but the least of which is that customers continue to receive emails. The maildir format in DA is not the same as the maildir format on cPanel, so you can't just do a 1:1 rsync of /home/user/mail to /home/user/maildir or /home/user/imap. It looks like:

    DA: /home/user/imap/domain.tld/user/maildir
    cP: /home/user/mail/domain.tld/user

    This is some logic that is going to take me a good while to script out I think, to make sure that I'm thinking of everything. But while I'm doing it, I'm curious if someone else has already done it and might be willing to share

    Did you see https://forum.directadmin.com/showthread.php?t=58066 ? Maildir format matches, so, rsync can be used.

    Hello!
    I've been tryting to transfer few accounts from cPanel to new DirectAdmin server. Apart from other issues with DA, I would like to point out couple things that I noticed:

    1) Rsync transfer does not work when PasswordAuthentication in /etc/ssh/sshd_config is set to no (might be obvious for most users, but for new ones that might be tricky to figure out);

    2) It is not possible to restore admin user from cPanel, because DirectAdmin already has an automatically set admin user.
    Now this one I would say could be changed. I personally would like to restore my admin account with all my personal and business domains onto admin account in DA. I assume others would like that too. How about making this possible, or giving users a choice if they would like to do restore onto same username or different?
    Or maybe there is some sort of issue, which forbids of doing this?

    I was also thinking of changing the username in cPanel, but it is not recommended, since it can break few things. So I am a bit stuck at this point.
    Would changing the transfered backup file name help? For example if I would change cpmove-admin.tar.gz on DA server to cpmove-adm.tar.gz? Would it still be restored as admin, or adm?

    (I posted this comment also in here: https://forum.directadmin.com/showth...749#post302749, but I realised that this thread is newer, so please remove the comment in that other thread if needed).

    Thank you!

    See the 2nd post if you'd just like to try it for a single or couple accounts.

    FAQ for new customers:
    http://forum.directadmin.com/showthr...460#post296460

    ---
    Known issues:
    * RoundCube data is converted from sqlite (like ./homedir/etc/domain.com/user.rcube.db) just since version 0.0.14, make sure you run the latest.
    * cPanel mdbox is supported in ver. 0.0.7, but hasn't been tested very throughly.
    * Mailman mailing lists do not get converted to majordomo mailing lists
    * Please make sure it's you who created cpmove-user.tar.gz backup for security purposes, because at this moment we fully trust the content inside, thus available on admin level only. This might change later.
    * DirectAdmin format for mysql usernames/databases is always username_database and username_user. cPanel has the same format, but due to max username/database length (https://forums.cpanel.net/threads/us...limits.630671/), is sometime shortens the username part in from of it. cPanel allows myusername_ to have a DB username with myuserna_. DA DB names/usernames always start with myusername_, changing this would create a mess, for example, you could have myuserna user owning myuserna_db1 and myusername user owning myserna_db2. The script converts username to be username in such cases, so, for some accounts you might need to change database username/name in wp-config.php or other files CMS uses. This should be rare though. Script output in such cases:
    Code:
    WARNING! us_wordpress cannot be owned by user, renaming database user to user_wordpress
    * JetBackup format doesn't include cpmove-user directory inside, so, for now these need to be converted manually, like (would store converted backup in /home/admin/converted_user_backup):
    Code:
    jetbackup=yes /usr/local/directadmin/scripts/cpanel_to_da/cpanel_to_da.sh /home/admin/user_backups/cpmove-USERNAME.tar.gz /home/admin/converted_user_backup
    chown -R admin. /home/admin/converted_user_backup
    Other things to take into consideration:
    * It's recommended to leave all the cpmove-user.tar.gz files on the system after restore. If there are bugs, or something goes wrong, it'd still be possible to recover that data.
    * Like any software - there might be bugs there, if you notice any - please let us know, and we'll try fixing them as soon as possible.
    * DirectAdmin supports a different feature set than cPanel. For example, DirectAdmin supports nginx/openlitespeed, MySQL8, rspamd etc., but it has no support for PostgreSQL or Ruby. So, if you have any sites using them - they'd need to be transferred manually.
    * Max username length is 16 characters for MySQL users by default, and 10 for system user. Max username length can be increased in /usr/local/directadmin/conf/directadmin.conf. You can find max length of your username in cPanel easily:
    Code:
    ls /var/cpanel/users | awk '{print length, $0}' | sort -nr | head -n1
    To increase it in DA to 16, for example, you can simply run:
    Code:
    /usr/local/directadmin/directadmin set max_username_length 16 restart
    * To make sure your MySQL username/database name is fine, I'd suggest upgrading your MySQL/MariaDB on the server (https://www.directadmin.com/features.php?id=2294), MySQL 5.7+ or MariaDB 10.x is recommended.
    * I'd suggest trying it with 1 account first, most preferably - the one with the longest database name/username (guide for this in 2nd post) to make sure you have the nameservers you need and that you don't hit any limitations
    * If you have user.tar.gz instead of cpmove-user.tar.gz, it will not work! pkacct forms cpmove-users.tar.gz. If you have a list of user.tar.gz files, and want to rename them all in current directory:
    Code:
    for i in `ls *.tar.gz | grep '^[A-Za-z0-9]*.tar.gz'`; do { mv -vf ${i} cpmove-${i}; }; done
    * If you have backup-...._user.tar.gz instead of cpmove-user.tar.gz, it will not work! pkacct forms cpmove-users.tar.gz. If you have a list of backup-...._user.tar.gz files, and want to rename them all in current directory:
    Code:
    for i in `ls backup-[0-9]*.*.tar.gz`; do { USERNAME=`echo $i | cut -d_ -f3 | cut -d'.' -f1`; mv -v $i cpmove-${USERNAME}.tar.gz; }; done
    * If you don't see the user in "Move users between resellers" list, please apply: https://help.directadmin.com/item.php?id=251
    * If you did not restore resellers first, all users were assigned to "admin". If you want to re-assign them to correct resellers after restore:
    Code:
    cd /home/admin/all_backups
    for i in `ls user*.tar.gz`; do { RESELLER=`echo $i | cut -d. -f2`; USER=`echo $i | cut -d'.' -f3`; /usr/local/directadmin/scripts/move_user_to_reseller.sh $USER admin $RESELLER; }; done
    echo "action=cache&value=showallusers" >> /usr/local/directadmin/data/task.queue
    /usr/local/directadmin/dataskq d

    MIGRATION STEPS:
    Steps to transfer ALL the accounts from cPanel server to DirectAdmin:
    cPanel server:
    1) Create a backup of all cPanel accounts on cPanel server and place them to /home/all_backups (make sure you have enough of space for them, if not, please read the suggestions at the end of the article):
    Code:
    mkdir -p /home/all_backups
    for user in `ls /var/cpanel/users/`; do { /scripts/pkgacct ${user} /home/all_backups; }; done
    2) Transfer /home/all_backups to DirectAdmin server:
    Code:
    rsync -avt --delete /home/all_backups/ root@your_directadmin_server.com:/home/admin/all_backups/
    We're done with cPanel server now. Let's connect to DirectAdmin server now.

    DirectAdmin server:
    1) Make sure your DirectAdmin version is at least 1.57.4 (as of time of writing, pre-release: https://help.directadmin.com/item.php?id=408), make sure backups at /home/admin/all_backups are owned by "admin" and that you have latest version of convertor script
    Code:
    cd /usr/local/directadmin/custombuild
    ./build update
    ./build cpanel_to_da
    chown -R admin. /home/admin/all_backups
    2) We finally have DirectAdmin backups in /home/admin/all_backups Now we can simply go to DirectAdmin "Admin Backup/Transfer" section, check "Backup/Restore Settings" (defaults should be fine) in Admin level and restore all backups from "/home/admin/all_backups" directory.

    That's it!

    -----
    If you have enough of space, I'd suggest leaving /home/admin/all_backups still there on DA server for a couple of weeks/months, if there is something missing in DA - you'd always have it in that backup.

    If your cPanel server doesn't have enough of space - it's easy transfer accounts one-by one directly to the home folder on a new server. The most convenient way to do this is to generate SSH keys on cPanel server using:
    Code:
    ssh-keygen
    Then you'll have your public key placed in /root/.ssh/id_rsa.pub. Just copy the content of it to your DirectAdmin server, file /root/.ssh/authorized_keys (if /root/.ssh directory does not exist - create it). This will make it possible to connect to DA server without any password (from your cPanel server). Now instead of steps 1) and 2) on cPanel server, just do this:
    Code:
    for user in `ls /var/cpanel/users/`; do { /scripts/pkgacct ${user} /home/all_backups; rsync -avt /home/all_backups/cpmove-${user}.tar.gz root@your_directadmin_server.com:/home/admin/all_backups/cpmove-${user}.tar.gz; rm -f /home/all_backups/cpmove-${user}.tar.gz ; }; done
    This would work fine if you had 2 servers. 1 with cpanel installed and another with DA installed, but what do you do if you just have 1 server and want to reformat the server with DA

    I have all then cpmove files saved on an external HDD

    Just rsync:

    From your cpanel:
    Code:
    rsync -rvz /home/cpusername/mail/domain.tld/user/cur/ root@daserver:/home/dausername/imap/domain.tld/user/Maildir/cur/
    Repeat this step for another user
    and then correct owner in your DA:

    Code:
    chown dausername: /home/dausername/imap/domain.tld -R
