MVPHi Poseidon1974
I would recommend-
1. First, keep your new vServer ready and tested. You can do testing by adding local host entry on the test systems. So, without having dns entry against new vServer IP, you can test app. Once, this is all set,
2. You are good to change the DNS entry and point URL requests to the new IP. If the URL is publicly hosted, then in worst case scenario, it take upto 24 hours to reflect DNS change globally. Also, some client system will have old cached IP.
So it would be better to have OLD vServer live until everything is sorted. So this will save you from having any glitch for the connectivity.
As per my understanding, with this you should be good with the migration. Also, it would be better to have this change under maintenance window.
Hope it helps!

CirrostratusHi,
Thanks , I already have a non-prod environment, to do the test, I think I will keep the same URLs and only create new NODES, in disable, which I will test in non-prod, by activating them, to answer your question, I am on local URLs, however, having different F5 LTM partitions could be a problem, I would like to create the new NODES on the new partition,
Thanks
