I just found out some GOOD news from our McAfee Professional Services Engineers on site handling our conversion from IronMail 6.7.2 to McAfee Email Gateway 7.6.3 with MQM 7.0.1.
Our Professional Services team advised that McAfee supports a mixed environment for a single email domain with MEG 7.6.3 \ MQM 7.0.1 and IronMail 6.7.2 HF5 \ Central Quarantine Servers. Previously, McAfee advised that this configuration was not possible. But it seems with a MEG 7.6.3 \ MQM 7.0.1 environment you can operate the IronMail 6.7.2 HF5 \ IronMail Central Quarantine Servers without any issues. Not sure exactly how this works, but our Professional Services team says it is now possible.
For those of you still strugguling with the thought of shutting down and taking your IronMail Central Quarantine Server offline and bringing up the MQM 7.0.1 and MEG 7.6.3 servers, it looks like McAfee has got a way for the two Quarantine Systems to operate within one email domain without any issues. This will definitely allow a smooth cutover from one system to the other without the "YANK and PULL" process that was previously reccommended.
If there is anyone out there who is already running MQM 7.0.1 and CQS IronMail 6.7.2 in the same environment, please tell me if you have come accross some unexpected issues with the way the end users are accessing the both the CQS and MQM at the same time.
I am concerned about messages getting lost between the quarantine process of the MQM vs CQS or vice versus. I just want to be able to make sure that our employees are able to login to both end user UI's and message digests without any issues.
Also can anyone tell me which quarantine system determines the message needs to be quarantined? What happens if policies on both the CQS and the MQM fire at the same time, which server has the "right of way" to quarantine the message? How does this show up in the logs? Will it show in the MEG logs or the IronMail logs?
McAfee tech support, if you have some insight on the issues that you see with both the MQM and the CQS operating and quarantining message traffic within a single domain, can you please share this information.
