Im going to be switching from cPanel to direct admin because i prefer Direct Admin more user friendly. To the point though, if i was to switch to Direct Admin would i loose all the users i have on cPanel?
I didn't write the converter, but I think you just take the cpanel backup files and convert them to DA backup files. Then you restore the User backups in DA, so it shouldn't really matter when you convert them. I'd save the backups somewhere, install DA, upload the backups, convert them, then restore the new files.
