I agree with Bill's approach but would add the creation of CDS4 before switching to CDS3 and using it as your alternate couple dataset while you are deleting and reformatting CDS1 and CDS2. That way you lessen the chance that you are called away from your desk while your system is running without an active alternate couple dataset. Also, if you are a GDPS shop, you need to use the GDPS sysplex management panels to switch your couple datasets instead of the commands. Another thing to watch out for is that you don't over allocate your couple datasets. You can increase the limits and switch to new couple datasets easily but if you ever over allocate and end up wanting to reduce the limits, you will be looking at a sysplex wide outage.
Hope that helps. Rebecca ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
