OM fix (delete all om objects and run rhinte report PA to OM)

there are a lot of relationship and object validity dates errors in the existing OM module

i am thinking of doing the following steps

1. switch off integration of OM and PA

2. change all number ranges into external

3. delete all objects in OM

4. run a rhinte00 report (PA to OM)

5. change back number range to automatic

6. recreate relationships manually thru PPOME

has anyone done this before? what were the problems you encountered? is there a better way to do this?

Thanks!
