We are trying to move from version 5.5 to 7.0. I have read through the uninstall/reinstall process described on pages 11-13 of https://s3.amazonaws.com/zertodownload_docs/Latest/Upgrading%20Zerto%20Virtual%20Replication.pdf
We’ve only updated in sequence, maybe when you uninstall Zerto, presumably the VRAs will be uninstalled at that time as well? I would probably go with installing NEW VRAs for 7.0 as they added a feature that allows you to be able to login to them via ssh key from the ZVM without contacting Zerto support. They mentioned upgraded VRAs would not be able to advantage of that feature.
Connie is correct – when the installer is ran to uninstall the existing version, it will also automatically uninstall the VRAs. This is why a user must export the VPG settings and delete all VPGs (while being sure to keep the recovery disks!) before uninstalling the ZVM (and thus automatically uninstall the VRAs as well). Once the new ZVM version is installed, you can install the new VRAs and finally reimport the VPG settings.
Thanks for the replies. We performed this upgrade several weeks ago, and while it went mostly according to plan, we had some issues with the uninstallation from one of our sites. We had to manually edit a file to enter the site ID back in to get the sites to pair up properly, then and only then could we import the VPGs and resume replication.
Zerto support was spot-on in helping us resolve that issue. All in all, it was a fairly straightforward process, it just took a really long time to remove all the VRAs and then to figure out why our VPG import was failing (see above).
Great to hear Jeff and I hope this info helps others in the future too!
