[cypher]

I think probably the most important thing is not to clean for a couple of weeks at least before & after the move (apart from spot cleaning pee) so all the substrate, wheel, toys etc smell familiar.
If you can make a familiar layout too it helps I think but isn't essential.
It can take them a while to adjust to the change so best not to interfere or be tempted to move things around unless something really doesn't seem to be working out & just let your ham settle in.
Some people let their hams play in the new cage a few times before the move but I never have, you can't put all their stuff in so I don't think it really makes a difference to them getting used to it tbh.
