Solved Upgrading from 15.5 to SP6 and after to 16

[GhigoBoi]

HI, I am trying to upgrade my Google Cloud based V15.5.5 to SP6, and then upgrade to V16, but I cannot find some clear directions. The majority of the post I found says that this should be an option on the Updates page, but my system tells me that it is up to date, I would like to avoid a full reinstall.

Thanks for your help!

This will get you to Update 6. You should be able to upgrade to v16 from the management console after that. Make sure you have snapshots/backups.

Thanks Cobaltit, so you are confirming that the direct installation is the way to proceed and there is no option from the SW itself? I wanted to confirm and verify this before proceeding. I have read the article you sent me several times, but on other posts I found different opinions.

All done, I am running now version 16.
Thanks for the support
