This is great tips.
I looked at the dbid update utility. That is very simple to use as well. Wow! the performance of the tool.
I think, the tool would add another benefit for the community when they use it, if the tool can do below.
1) A message after the task is completed.
2) In Global changes, it's very useful, if you can add "Project Name and DB Name Boxes". It's because sometime like during migration/upgradation you may want to change these 2 parameters.
