Joe,
I'm thinking do you really really need to get rid of Vault1 for a particular reason, or is this more a cosmetic tidy up after moving things around?
I'm guessing that combined, vault stores journal and email take up more space than vault1 (a legacy vault store perhaps?)
Also, if legal hold is likely to be anywhere, it is more likely going to be on items in the journal archive (although it could realistically be anywhere)
Do you actually even want to keep the data in the archives contained in Vault1? If you want to delete the vault store itself then that sounds unlikely.
Anyway, if you move the archives contained within vault1 which you need to keep, then as Alex said, use another vault store in another vault store group OR use a vault store in the same vault store group with sharing turned off.
You can then delete all the archives contained within vault1. If you didn't need to keep any, then just delete them all. Any items which are shared will not actually be removed, but their ref-count will be decreased and the items will remain in the partitions associated with vault1. This could then be consolidated down so all partitions are within the same volume. Close the last partition in vault1 and make sure it is not the default for any new archives created. You would not be able to remove vault1, but then its existence would then be simply as a 'reference' vault store for the other two remaining vault stores.
My point is this though - if you decide to move email and journal to a new vault store group, or if you decide to simply delete the archives from within vault1, you are going to end up with the same data on disk because the remaining undeleted items are referenced in the journal and email vault store. If you moved the archives then they would need to take copies of this data. Thus really all you have done is a bit of reorganisation in the vault admin console and data shuffling for no real practical benefit I can see.
Regards,
Jeff
