[Dovecot] Platform change, considerations?
Hello!
I am switching hardware platform for my dovecot 1.0beta3 installation. From Sun Sparc (SS4) to Intel i386. OS platform will only change from OpenBSD 3.7 to 3.9. From Dovecot 1.0beta3 to beta8.
Is there anything special to consider, in terms of endianness or other incompatibilities?
I plan on a fresh install (compile) on the new machine, migrate the settings manually (by hand), test the new server and then migrate old mail. Can I just mount the disks and copy, or should I go through NFS to be safe from potential endianness problems? Or perhaps copy with IMAP using my Thunderbird client?
The live switch (the old server is in production) isn't that delicate, several hours downtime is OK. There's a backup server that can receive any mail I might loose during downtime, which can be copied though IMAP later.
Thanks for any input! /Peter

if you're migrating the mail rather than physically moving the disks the only consideration I can think of would be any endianness issues in the Dovecot index files. you can safely delete them and they will be re-created. it would be worth trying this before you migrate - and if you discover that there is no need to rebuild the indexes, then don't bother.
the same may apply if you're moving the disks, but you'd have to check whether OpenBSD has support for endian-independent access to the filesystem.
other than that, it should be very straightforward :)
