Is there a way to keep users from logging into ServiceNow while instance is being upgraded?

[Vasavi Kotha1]

We are upgrading SN from Helsinki to Jakarta, we completed all the testing in sub production instances and everything worked well. But while upgrading our prod instance we would like to keep users from logging in as we have a few groups using service now 24X7 creating tickets, which we do not what to happen during upgrade for obvious reasons.

Are you using SSO? If so, you can turn off the Login Script/rule until the upgrade is completed.

Having said that users can still enter the instance via side door, but I highly doubt if your users know the trick.

Please hit correct based on the impact of response.

Thanks!

We do use SSO. Where do we find the Login Script/Rule? Did you mean the Multi-Provider SSO module?

Yes you can find it under SSO module as Login script.
