Inconsistent CIF_IM* tables after client merge

Experts

Standard RCIF* reports are not correcting the issues with inconsistent entries in CIF_IM* tables that are copied from another ECC system alongwith the int models which to begin with are fully inactive. This obviously means there are entries in CIF_IM* tables that 'think' that int models are 'Active'. So attempts to activate int models does point to bad table entries in CIF_IM* tables. This is all for all master and transaction data... almost all know int model objects have run time models.

How do I fix this quickly? without having to delete and recreate integration models? Will latter also delete all CIF_IM* entries?

Thanks
