I'm sorry to inform you that I don't believe this can be done.
Can be done,contact your VAR for this.few changes in DB and registry will have to be made.
*_not worth the trouble
I wouldn't say not worth the trouble, if you really feel it needs to be done. We do this on a monthly basis for our test vault......we append the word "Test" to the vault name.
As Ravi says, there are a few place it must be changed. Off the top of my head there are two tables that must be updated and some places in the registry on the database/archive servers. Also a bigger headache might be all of the clients that need updating as I believe their registries will require updating.....possible the local view may need to be deleted and recreated which will mean everyone needs to have ther files checked in.
You VAR will be the best person to walk you through all of this.
Thanks to everyone for the input. I think I will set up a duplicate copy of the vault by restoring from a database backup to a different database name.
