Be aware, a flash notice was just issued for users who are planning to upgrade or have scheduled maintenance this weekend to upgrade from QRadar 7.3.x to 7.4.x. The flash notice describes an upgrade error where a conflict with an auto-deploy file can cause hostcontext service does not start as expected after the upgrade to 7.4.x completes. If you received the 21 October 2020 weekly auto update and decide to upgrade from 7.3.x to 7.4.x there is a workaround in the flash notice to prevent the service issue.
There is an APAR pending and administrators are being alerted to this issue in case you plan to upgrade before the next QRadar weekly auto update.
Note: The URL for IJ28895 does not resolve yet, but should be live soon. If you are planning to upgrade from QRadar 7.3.x to QRadar 7.4.x, you can subscribe to the APAR to receive updates when this issue is resolved.
If there are questions, let me know.
