Hi,
Today, I install centos 8 and CWP for centos 8, I upload my cpmove file, select cPanel Account Restore and select public_html files and mails accounts.
At the finish indicate all ok but when access to mail accounts are empty.
If I enter via SSH, in /VAR/VBMAIL are all mails accounts.
I try to connect, but not connect, I create one account then, I connect and appears all mails.
This procedure is the same that I use with centos 7, and with this, restore well all mail accounts.
Thanks and regards.
