All the websites and email accounts have now been moved. There was a little hicup as the pleskbackup (8.6) did not like me, so I had to backup and restore each websites manually.
There was also a problem with the/usr/ partition overfilling and crashed the Plesk CP by filling up /usr/local/psa/PMM/logs, I had to move some restore logs as they were huge (3.4GB). After that, panic over and all went ok. (I took the safety option not to delete the files as you never know what Plesk can throw up at you, but it did not seem to affect my work, so I don’t know what these files are for except after action review? yes I fancy looking at a 3.4GB log file!)
Plesk does seem to have some issues regarding disk space…
Anyway, the site are all moved and all is working well again. The DNS will be propagated by tonight, as I can already ping the new IP…
The Urchin stats will be replaced by Google Analytics, it seems quite good.
