Issue/Introduction

When executing the post upgrade steps the NewMM.pl process looks like it hangs on this step:

Would you like to convert the eligible source model(s)
to this new model type? (y/n): y

How can we check that all have converted correctly?
and chow we can check that this process didn't corrupt anything?

Environment

Release : 22.2.x, 23.3.x

Resolution

VIB is "view information block" which is how we build out the topology placement. So if it cannot restore the VIB information the default placement will be used in the Topology, and not where the model was prior to running the script.

If the devices are being restored to the default location, We would not worry about this message. Please confirm this, or if you noticed any side effects.

We did find out that this may be caused by an obsolete attribute or model type as some customers have also reported this when running the newMM.pl script and they had no other side effects.
