This last week we stood up our 9.6sp1 test environment and have been putting a few agents out on production endpoints after completing our testing. The 9.6 environment is working great.
At the same time we still have the majority of our endpoints on the 9.6sp3 agents.
Both 9.5 and 9.6 are using the same keys and certs.
We are seeing and have been patching endpoints on 9.6 without issue.
In the 9.5 (legacy) system we are not seeing any new vulnerabilities from this last MS patch release.
Is it not possible to run concurrent systems with shared security?
Is there anything I can do to get me through this month's patching without quickly pusing new 9.6 agents to all endpoints?
