We've recently upgraded from DLP 2.0 to 9. 1 on ePO 4.0. Since our 3000+ clients are still using DLP 2.2 Patch 2 (18.104.22.168), we enable this backwards compatibility during the upgrade. We've only installed the 22.214.171.1242 agent on 3 machines for testing.
What bothers me is that there was no visual indication of errors during the migration/conversion of the legacy DLP 2.0 policy. In addition, we have several other device rules actively being used in the environment - how do I know these rules are working/blocking as expected? The only reason I found out things weren't right is because another user said her iPod was suddenly working when it hadn't previously.
McAfee has yet to figure out what happened, but assured me that once I created this new device rule, all the policy files were re-written, and that the other device rules 'should' work. I am not buying this, and if users suddenly can access their previously blocked devices, they definitely aren't going to step up and let us know that there is a 'problem.'
Has anyone else had issues like this?
I have sme question~ Is DLP 2.2 patch 2 Be able to upgrade to DLP 9.1? if want to keep old information?
