Using Multiple Versions

[dalty]

We are currently running v7.1.827.

I am having issues when moving fragments on a sequence diagram messing up other parts of the diagram.

I see in the release history that there are fixes to fragments in rev's 829 and 830.

It is not feasable to upgrade all workstations to rev 830. Is it possible to run rev 827 and 830 against the same database ?

In general, even an upgrade between different versions shouldn't cause a problem.  Upgrading between builds within a version definitely shouldn't.
