partition exceeded maximum... can I make it bigger?

[7YD]

DA on Centos 7 sends me the message: "This is an automated message notifying you that the following partition(s) have exceeded the 95% threshold:"
I've checked what can be deleted... and.. delete that part. Following some threads is this forum
But that is only moving the problem to a point in the future.

What is a good solution to solve this:
- upgrade the partition and make it much bigger ? Is that possible? is it safe for the data etc. (on the disk there is plenty room left)
- put some DA users on another partition.. Possible?

So I need a little bit advise and help about this.

if you are talking about /home you can do what fits you better.
- extend partition by free space from this disk (lvresize or boot in rescue and resize any FS type)
- replace partition by another with more space (from rescue, copy data to new partition, swap them)
- add additional partition from another disk for few users (if they need additional IOPS)
