Hi. We are starting to plan our upgrade. Since this is our first upgrade, we would like to do 3 maintenance windows. We are in a cross-vCenter deployment.
Our windows would be as follows.
1. NSX managers and controll cluster
2. Host upgrades
3. DLRs and Edge gateways
My question is how long can we run between windows? Could we do each window on a Saturday, so basically a week between each window? Thanks,,,
Yes , that is perfectly fine. I would recommend to complete NSX manager (both the sites) and controllers are in one go and rest of them based on downtime window. It took me a month time to upgrade 300+ edges , so all depends upon the use cases and critical nature of application hosted as not everyone will get a green signal to upgrade the full stack in a week.
Holy cow that is a lot of Edges! I cannot even comprehend that. I only have 4 edge gateways. I hope to be able to do everything in 1 day. It seems so. I have just never done an upgrade so a bit nervous. We do not have a DEV environment to try it on. Thank you for the reponse!
