FWIW, I migrated some 70+ wikis to a new server. It went far smoother and faster than what I had allotted. I'd already done some restores, so I had the process down for individual wikis. I now host over 100 wikis. I make full backups weekly to an offsite 1tb RAID 5 NAS, and I make daily automated backups of all databases (locally stored - RAID 1). For the migration, I brought down the old server's external access (httpd, vsftpd). Shut down MySQL. Did a final mysqldump of all dbs. Copied the db SQL to the new server. Copied all the old folders over (by mounting the old server's root as a mnt on the new server). Copied over the httpd.conf's virtualhost entries (all at the end). Did a mysql < .sql to restore the dump to the new server. Started httpd again and everything worked great. I've also done dozens of upgrades from 1.3.x and 1.4.x and 1.5.x to a 1.7.1-based baseline. For those, I rename localsettings, copy in the new files, run the install, update the newly-created localsettings with any customizations (always at the bottom). No problems. - MHart
