ontape warm restore question

IDS 94FC8 using ontape for a restore. In performing a warm restore of a dbspace, how critical is it to have the exact same size and number of tempdb spaces? I have a tape from a previous period before we added several new tempdb spaces. I would rather not modify the system unless necessary to revert backwards or create a new instance just for this restore. The dbspaces for root, phy log, logical log and the to-be-restored space in question are the same. The manual talks of critical spaces being the exact same in size, name, offset, etc. Yet I am not sure if temp dbspaces is part of what they call the critical spaces.

Also, will the fc patch version be a hindrance? We have started this instance with fc2, applied fc6 and then fc8. The ontape -s -L 0 was from the fc6 patch.

Thanks in advance,
Doug
