This one hit home as we have PTC as well. How do other, modern change
management systems handle this (open source or commercial) ?

Yeah, Aldon worked in a similar manner...

You could specify pre/post install programs. Also IIRC there was a way to
specify a custom conversion program.

Thanks Steve.

You're right, Implementer support got back to me, and they have method
of adding special commands prior to moving the file into production, and
post move commands as well. It does require a custom program to handle
the data conversion.

Peter -

Some manual intervention may be necessary.

I believe that this is what we did using Implementer:

1) Make a copy of the data file in another library

2) Promote a delete to remove the file in the to-library

3) Promote the new file object with a PTC object code which does a
CRTDUPOBJ to duplicate the file object from the previous environment
using
DUPDATA(*NO). **
(**If you don't have such an object code, create one. )

4) Create and promote a special program to convert the data from the
old
file format to the new file format.

5) Either
a) Manually call the conversion program after the file promotion
/or/
b) Implementer gives you the additional ability to call an
"After-Promotion command" which could call the conversion program

Subject: Using change managment to promote physical file with field
change from numeric to alpha

How do the various change management systems handle the promotion of a
physical file where a field is being changed from packed numeric to
alpha?

My customer is using PTC Implementer, and it works up to the point
where
it is trying to copy the data from the existing file (with numeric
field) to the new file (with alpha field), then fails

Is this just a situation where manual intervention is required?
