I had a doubt regarding upgradable contracts.

I have a upgradable token contract.

I want this contract to be used in an another upgradable contracts ( which is a staking contract, for example)

Now, will the interaction between these 2 contracts be the same as we do with traditional contracts?

Or there is some other IMPERATIVES that I must keep in mind while using the upgradable token contract in the upgradable staking contract .?
Please let me know
