how to disable all access to our Appian site

Question

Hi, 
 Is there an easy way to disable all access to our Appian site temporarily? We are doing some database cutover and want to prevent users from initiating processes in Appian that my update the database while we are doing a cutover. 
 Any suggestions? 
 
 Thanks, 
 Gary

If you are looking to prevent the user from initiating new processes then you can change the security on those process models to admin-only while the work is being done, that way users can still access records and reports but cannot kick off new processes. When the work is done simply change the security back to the original state. If you're also worried about users working on in-flight tasks then this approach may not be a complete solution. 
 
If you need to prevent users from hitting Appian at all and you manage an on-premise instance, an option would be to redirect the url to an html page that tells the user the system is under maintenance. When the work is done you can remove the redirect and users will hit Appian again.
