Make sure that if you are upgrading from 3.30 to 7.0 you backup your data
and filestore directories.
My upgrade did not complete and I was then unable to log into my original
task server. I was able to restore them from backup and log back in.
So far I have not been successful in upgrading from 3.30 to 7.0.
If anyone out there was succesful, I'd appreciate any tips.
