Existing filter with new filter in same tank

[NewFishNewbie]

hello, i want to get an external canister filter to replace my unsightly internal filter, the existing filter is cycled. Is it okay to put a new filter in with it?

Of course! You can also take everything from the Internal filter a stuff in the canister.
