1. Hazel, for sure. It got rid of the Baxters, then had Hazel working for a different family in the end.

2. Suddenly Susan. It completely shifted gears after one of the cast members killed himself. IIRC, the entire cast was rid of in the last season and Susan's job moved to a different location with a new boss.

3. Joey Bishop Show. Started off as a family sitcom, then became a showbiz sitcom. Went through several dramatic cast changes and switched from black and white to color to black and white again.

4. The Odd Couple. Went from no audience in the first season to live audience in the next.

5. The Honeymooners. Started out as a skit on the Jackie Gleason Show, became its own show, then came back in a number of color specials in the 1960s and 70s.

6. Too Close for Comfort became The Ted Knight Show, with the same characters more or less (except the two daughters) and a new setup.
