Rich Welcome to TR.
what size tank are you going to upgrade to.
the reality is if you go to anything over a 15 (maybe 20) gallon system the cycle might be too strong for your livestock.
i would suggest setting up the new tank with some LS and
LR, let is cycle, then transfer the LS and
LR from the old tank. it might be a "little" rough on the fish, but should be ok if you go that route.
i know i have done a few shows on replacing tanks, or in place upgrades, so those might be a place to start.
