Hi and welcome to the forum

If you set up the new tank with new water and let it run for a few days, you can take half the old filter media/ material and put it in the new filter. Then put that on the new tank for an instant cycled tank. Add fish 24 hours later and you're good to go.

About 2 months. Hence the reason I suggest putting half the old media into the new filter and just get the new tank going.

If you only remove half the old filter media, the remaining bacteria will repopulate within 24 hours and it's very unlikely the filter will crash.

So just swich out half the bagged stuff

If the established filter has a sponge and bag of ceramic rings, either swap the bag of ceramic rings or swap the sponge.

It has a bag of rings and a sponge

They will both hold bacteria so just swap one of them over
