Issue:

Upgrade from Current Branch Previous Version to Upgrade Latest   appears to be hung on "Installing..." In my CMUPdate.log file it just repeats:

"Waiting for changes to the "\\<server FQDN>\<DB?>\inboxes\cmupdate.box" directories, updates will be polled in 600 seconds...  $$<CONFIGURATION_MANAGER_UPDATE><11-29-2016 13:35:46.651+480 <thread=1544 (0x608)>"

There were a couple of errors earlier in the Install process (passed all pre-reqs), so I'd like to restart the upgrade.  However, all options in the console are grayed out, and the install process hang continues after a reboot, or end task of the CMupdate.exe process.

Solution:

Note: Make sure you have backup before performing below task Application level backup and SQL Level.

Follow below steps to rollback:

1. Backup sql.

2. Use command Delete from CM_UpdatePackages where PackageGuid=' '  (your Current Branch Version upgrade package guid)

3. Delete from EasySetupSettings where PackageGuid=' '

4. Clear EasySetupPayload folder(C:\Program Files\Microsoft Configuration Manager\EasySetupPayload)

5. Stop the SMS_SITE_COMPONENT_MANAGER and SMS_EXECUTIVE services

6. Start the SMS_SITE_COMPONENT_MANAGER service (this will automatically start SMS_EXECUTIVE)

7. wait for few hours to see whether the package status came back to available.

If no progress, you may use respective versions baseline media to upgrade instead of in-console upgrade.

Happy Learning!!!
