Re: Upgrade/migration time estimates

The upgrade doesn't take long at all, say 30 minutes for the actual install and upgrade. However the preparation, backing up DB, changing paths, .profiles, backup scripts documentation etc. is significantly longer !
With the migration, assuming you are using the migration utility and not import / export, then I would estimate the migration to take around 90 minutes. Again, it is the preparation, and the running of the catalog upgrade scripts that can take an hour or more.

Good Luck
