We are about to convert from JIRA onDemand to JIRA on-premisis.
After the conversion, I plan to keep the onDemand instance around for a few days incase there is some question about the data that was converted. I will change the banner, etc., in the old system to warn people not to make changes.
But it would be better if I could make the whole thing read-only. The new and old instances will look very much alike. I don't want some product owner spending several hours updating a project before discovering that s/he was doing so in the old instance.
Ideas anyone?
