So I once had a thriving shrimp tank, with RCS, yellow shrimp, bumble bee shrimp and a couple of others. Including Vampire shrimp. All was good for a nice long while, then all my shrimp disappeared over about a 2 week period. No trace of them at all. Soon I was down to about 4 RCS and the 2 vampire shrimp. Bought 20 more RCS and about a month later pretty much all gone. I don't think the vampire shrimp ate them, my water parameters are good.

Anyways, bought an established tank from a guy. About a colony of 30 RCS or more. Nice berried ones. Now, should I introduce the Vampire shrimp into the new tank? or not risk it and leave them in the old tank? Also, should I transfer the one or 2 RCS that are left in the old tank?

Thanks in advance

Vampire shrimp don't eat anything but floating particles and microscopic organisms. So, no danger in introducing them. Your tank just lost its cycle...that can happen easily in shrimp tanks.
