How to rejoin correctly after CS and MV Deletion

Hi,

if I have to reinstall FIM (using only Sync Service) und I have no backup. How is the correct way to rejoin the objects?

I have two Management Agents. Import from MA A and Export Objects to MA B. Object Deletion Rule is: Delete Objects if disconnected from MA A.

My plan would be:

1. Full Import MA A

2. Full Import MA B

3. Full Sync MA A

4. Full Sync MA B

In Test Env I did this but I got thousands of errors when executing Step 3 (object already exists) and in step 4 disconnects. in MV there is no object created.

Thanks
