migration issues
Here's the list of issues I'm aware of. (Marking these off as I go along)
control panel not workingodd mailbox permissions on argondatabase connection problems from argonout of memory errors with phpperl missing ImageMagick librariesbroken link to phpmyadminsuexec problems on argonSpamAssassin not runningbad imaps/pop3s certificates
Update: If you use an IMAP mail client and suddenly can't see your folders: get rid of the ~/mail/ prefix in your server settings. The new IMAP server uses this by default.
Update: If you have previously compiled any custom binaries on the old servers, you may need to recompile them. The new boxes are running a 64-bit version of linux so your 32-bit programs will need to be recompiled.
Update: the ssh fingerprints for the new boxes are at:
https://secure.sabren.com/cornerhost/prints.txt
Update: SquirrelMail settings and preferences were lost. This actually happened a couple days ago. My merging script accidentally wiped out everything on secure.sabren.com (the control panel, the main cornerhost site, etc). I restored most of it from backups, but the SquirrelMail settings are stored in an odd corner of the file system that wasn't part of my backup script. Nobody's mail got lost, but any settings configured inside squirrelmail are gone for good. The main casuality seems to be address books. Sorry. :/
