When I try to restore a backup from Portfolio 2.0 to 2.1, I get the following error message:
There is a known issue in Portfolio 2.1 and later where restoring a backup created in Portfolio 2.0, 2.0.1, or 2.0.2 will fail, and leaves the server in an unusable state.
Users who want to do a clean install of Portfolio 2.1 or later, either on a new server or to replace an existing installation, should install Portfolio 2.0.2, then restore a backup. Once you have determined that the restore was successful, you can do an in-place upgrade to Portfolio 2.1.2.
If you have problems with the migration, contact Extensis Technical Support.
