MS Tenant to MS Tenant Teams migration

Looking for a cheap if possible free solution to migrate about 20 Teams all channels and data. I dont care about Teams messages or anything else for that matter. I just need data stored in channels. I've purchased Bittitan license for Email and OneDrive migration and that went well.

Now i'm trying to save a bit of money by doing it as cheap if not free as possible. I used to use this nifty tool Air Explorer and it worked really well but since new tenant is a Geo Location Air Explorer cannot see Teams in the new tenant.
