Mark, I am assuming that all systems in the plex are using the same mastercat. Check out IBM Redbook - ICF Catalog Backup and Recovery - Look at Case Senario #7. This explains two ways to do it.
http://www.redbooks.ibm.com/redpapers/pdfs/redp4212.pdf Doing this over a period of time may not be a good idea unless you can be sure there were no updates to the old mastercat.

Does the answer change if the source catalog is the system master catalog/ Our master catalog was defined with the imbed/replication options and we are looking at the best way to migrate to a new catalog without the attributes. It is a six member sysplex and we would really not want to have a sysplex outage for the catalog switch. IPLing one at a time over a period of time would be fine however. -- Mark Jacobs Time Customer Service Tampa, FL ----------------------------- How we behave toward cats here below determines our status in heaven.
