I’ve been working on this topic for several Provider-1 customers over the past few weeks. If you want to move a CMA to another MDS, you normally could just use the ‘cma_migrate’ process. Well it turns out that does not work if VSX is used within the CMA.
There is an internal document on how to migrate a CMA with VSX being used. I have seen the document, and the process is very ugly. It looks like the best way is to setup a temporary MDS and use the HA feature to automagically copy over the CMAs to their new home. I am working on a document that will clearly layout this process. Should be up in the next few days.
