If I had a running VCF deployment with multiple workloads already deployed on this from vRA and wanted to move all these to a new VCF implementation, how easy would this be?
My main concern is around all the workloads which have been deployed using vRA, if I shift them to an entirely new vRA instance on the new VCF will this be a world of pain?
This is the same as if you were to migrate workloads between two separate vRA environments. So a better place to get an answer would be the vRealize Automation Tools group. The answer for generic vRealize Automation environments would apply for Cloud Foundation as well.
However, it could be a good idea to open a Support Case to get extra insights on this scenario.
