Version 5 versus Version 4, are the filesystems compatible?
The upgrade between versions 3 and 4, had a incompatible file system. You had to use the same version.
What issues should we expect between version 4 and 5?
Example of where I am going, should all users be on the same version? It would be lovely if we could just upgrade as needed not all at once. Stagger it, and not have people asking wtf, when changes between Schema Compare version cause issues.
ie, avoid chasing all users down. hassle.
eg I found one person still on version 3 yesterday. luckily he does not edit privileges
