Moving to another Server -> Problems with "maildir" etc.!!!

Hello Everybody!

We change now to new Servers and all account must be copied to the new server! Furthermore we want to switch fron "mbox" to "maildir"...

With tests with the switching to "maildir" we had problems with Horde. Horde does not recognise the maildirs and the "main-account" now only himself - the other mailboxes are not there...

New mails are ok in the maildir, but the mailboxes with already existet are not convertet. Also subfolders are not createt...

Do somebody have some guide, help or howto for this? Our Cpanel version is 10.8.0R58.

Greetings and THX!!!
