Evicting a tenant while owner occupying a two family

[J.R. Coffin]

Own and live in a two family and am just starting the eviction process with the downstairs tenant. Once they vacate I want to move into their unit and make a few repairs. In order for this process to not to entirely suck money out of my pocket (their rent currently covers most of the mortgage). I’m wondering if I can rent out my unit and move in with a friend temporarily until they vacate. Would that cause issues with my owner occupancy status? I’m hoping it’s only for a few weeks but i also haven’t been through an eviction before and cant predict the future.
