A fish like that is like an old friend. I'd sure hate to have to sell, trade, or give away the fish.
I'd give the old guy a chance in the new tank. There may be no issues at all. Plecos, when they get big, sometimes get lazy, and are not too interested in stirring things up.
If he doesn't work out, you can always sell, trade, or give him away.
