Test whatever you are going to do on a smaller system ( test system ) with a smaller amount of data first so that you know what your plan is.
Then start figuring out what will change and what else needs to be verified before doing this on a larger system.
I recommend that you work with your DBA and not some internet newsgroup on figuring out what your plan should be and coming to an agreement that includes a step by step planning and verification process. Received on Thu Jan 07 2010 - 07:10:01 CST
