What have people found to be the best way to remove a PMC Update VRC?

I have several PMC Update VRCs that are no longer in use which I'd like to remove.

Are there any "gotcha's" to be aware of?

Any lessons from experience you could share?

Lastly, what steps--if any--did you to take prior to doing this?

Turns out that to remove the PMC Update VRC,
solutions must be at "Available" status (not "Installed")
to be able to
"disconnect solutions" ttpmc2202m000 and then
"delete update VRC" ttpmc2241m000

According to the Baan support person I spoke with, the only way to get the solutions which have been installed back to "available" is to either:
a) UNinstall them
-or-
b) hack the table via GTM or SQL update query to change the status field.

Since UNinstalling them would take hours as it would want to put back the previous versions (which might cause side-effect issues), we went with b) and modified the status for field rsta to "1-Available" in the table ttpmc201 (after taking a backup).

Note-1: Be sure to have a backup as well as test this on your test system before implementing on production.

There is a PMC cleanup session, which can be used to delete the PMC Registry for an Update VRC. The help info of this session describes the steps, which you have to perform to remove everything of an Update VRC.

I did deleted the updated VRC just like what Baan said...change the status of the solutions from "installed" to "avilable" and disconnect the VRC and delete the Update VRC...it did work for us.
May be some other better ways also there....
