I use a cheap pair of Chinesium nippers that came with my 3d printer for the thick quick and dirty cut at the sprue gate and a pair of $14 Toenail nippers for the close clean cut stuff. Then I finish up with diamond file and a 10000 grit glass burnisher.

Server migrations are never fun, believe me I know. Best advice I can give is make frequent backups and verify the data on the new system before deleting it off the old system. Also, a backup of the new pristine server before migration can be handy if things really go south.
