How to correctly transfer storage to iRedMail?

Question

Mail server

Can you please tell me how to correctly move the storage to iRedMail (under CentoS)? That is, from /var/vmail.....
To a directory with a large space, that is, directories like /home... Or how can you increase the size of the root without painfully?

Answer 1

Try using a link, for example:
1. copy everything to a new (larger) directory.
2. rename the original directory to something else.
3. In place of the original directory, make a symlink to the new directory via ln -s.
You can also try using mount --bind:
1. copy everything to a new (larger) directory.
2. rename the original directory to something else.
3. create an empty directory with the name of the source directory.
4. mount a new directory there via mount --bind.
