Versions of application "8.0.6.3522" and configuration "7.18.4" are incompatible

Hello, we updated our QA system to 8.0.6 a few weeks ago and everything had been running smoothly until today.  We are now getting the following error.  We have not made any changes to the configuration files for weeks so don't understand what caused this or how to fix it.  Please advise.

Hi, I've had this exact error message before. I got it when trying to update my local development environment by updating the binaries and restoring the database backup of my previous version into the new version (which is not the right way to update environment versions, see below). Quick question, I assume this is an on-prem environment and if so did you use the update guide utility to perform this update? 
https://academy.creatio.com/docs/release/update-guide/update-guide
It's necessary to use this utility for all environment updates to newer versions as it performs metadata updates at the database level that otherwise do not get made producing this error.

(Note, if using the updater for versions beyond 8.0 you may need to raise a support ticket requesting the scenario file and binaries as the downloader script did not create those for me after version 8.0.1)

Hello Francine,

 

Thank you for your post. We already processed your request to our support team and will provide you with a resolution in scopes of the request placed to our support team.

 

Have a nice day!

Vishay Kerai,

 thank you so much for your response and sharing your experience!  

This is an on-prem environment and we did use the update guide utility to perform the update.  We also used the scenario file and binaries Creatio provided.  The oddest part of this issue is that it occurred weeks after the update finished successfully.
