New boss wants me to handover all my staff to her for appraisal. Signals?

Sounds like a civil service or a stat board department that you are working in. Only civil service and stat boards can afford to have so many levels of supervisors, and at your level with only 2 subordinates. So if this the case, then maybe they are streamlining and right sizing to reduce operating budget.

If you are indeed working in a CS or SB department, they are unlikely to (and cannot anyhow) sack you. Since your supervisor had already asked if you want to consider transferring to another department, I would suggest you take up the offer. It is clear she doesn't need you to be another layer between her and the other staff. Remember, she needs to justify her position too!

Because of this I feel her act is slowly aimed at moving me out of all the office operations.

I also did an appraisal with her 2 weeks ago. It was 4 minutes long and there was no talk of growing me into any area, rather, the immediate topic was if I am interested in any posting out.

When your boss talks with you for more than 25 minutes trying to justify why she wants to move staff who report to you to report to her instead, and in contrast spends 4 minutes doing your appraisal, I think it's quite telling.
