Yokohoma Release

[Felix16]

We’re currently facing several issues after performing the Yokohama release upgrade on our client’s development instance (on-prem), which are unfortunately blocking us from continuing our development work – it’s been over a week now that we’ve been stuck due to missing functionality and unexpected behavior.

Some examples of what we’ve observed so far:

• In Flow Designer, all action buttons have disappeared. We’ve already tried repairing the plugin and clearing the cache, but that didn’t help.
• In Agent Workspace, the Activity Stream is missing. I’ve already added it to the form layout again, but comments and work notes are still not showing (acls are not affecting it, as they´re as they were)
• Also, previously removed elements like the Inbox have suddenly reappeared.
• There were a few other issues too that some of our colleagues were able to fix directly, but we’re still testing and finding inconsistencies.

I’d really appreciate your view on the following:

• Is this kind of behavior something you’ve seen before with Yokohama upgrades? Or could it point to something that went wrong during the upgrade?
• What would you recommend as next steps to analyze and resolve these issues?
• Are there any known issues or best practices for post-upgrade checks we should follow here?

Thank you 🙂

What has NowSupport told you? Because that should have been your fist step over a week ago after noticing the issues. If it's due to OOB stuff that breaks on an upgrade, you should contact them.

Since you are on premise, there is more that can go wrong. Have you walked through all the steps in preparation for the upgrade, including checks on hardware and settings? Do you have any errors in the upgrade logs? 

The fact that previously removed elements are suddenly back, could be explained by them just being part of the platform and deletion will be overwritten with an upgrade. If it was inactivated, you should have had a skipped change to retain your customization. 

Since you haven't mentioned logging this with NowSupport, do that as soon as possible. We can't tell you if it was something going wrong with the upgrade, because we can't access your instance and most of us also don't have access to the on premise documentation, since ServiceNow hides that for any company that is not on premise.
