DB2 V8 NFM/ENFM migration

DB2 V8 NFM/ENFM migration
Hi List,

We are in the process of migrating from DB2 V8 CM to NFM. However, we've
encountered an issue where a number of our third-party vendors are not yet
ready to exploit V8 NFM. To expedite the process of migrating, we've
decided to migrate to NFM and then convert back to ENFM, thus disabling new
functions. My question is: is it possible for a DBRM that was created
within ENFM with NEWFUN set to NO to be re-bound in a V8 CM subsystem? We
have multiple development regions and my plan is to have the ENFM
development subsystems in place for a period of time, so as to perform a
more comprehensive regression test. However to do this, we would have to
be able to migrate from the ENFM development subsystems into a V8 CM
production subsystem. Our migrations are accomplished by moving the load
module and rebinding the plan/packages. Will this be possible under the
scenario I just described?

Any and all suggestion would be greatly appreciated.

Thank you,

George,
IBM recommends the time window between ENFM and NFM be
short in duration. That said, I would recommend
deferring any migration changes for applications until
the ENFM testing is completed. If that is not possible,
you could migrate to ENFM in production and then do the
application migrations.

The scenario you describe seems too risky to me.

Regards,
