I recently went through this through my daughter, who sold her condo and bought another place. I had her 2 cats (which by the way are all intro'd, not new to each other) who were new to my place while she was showing her condo.
She brought their toys, beds, food and water bowls, blankets...everything that she could of theirs. Cat towers, etc. I had them in my finished basement, so having as much of their stuff as possible with their scent on it is what you want to do.
It would pause things and may have to do some reintro-ing in your new place, so will take more time. But they can adjust.
C calicosrspecial and others will have more to say!
