You may try to restrict an access to K2 artifacts by managing Category Security in the K2 Management site.

In a few words, it is possible to manage an access to each form/view/SmartObject separatly or manage an access on the category level. You can temporary restric an access for all users to artifacts under the application category and revert it back after upgrade.

Of course, thanks for that. That’s done the trick, can block on categories which is ideal for stopping any access while it’s being upgraded

you can’t … you just need to inform manually to users.

You can do both - inform users and also use category security to block access, trust me i’ve just tested it earlier.
