Upgrading Mail Security for Exchange

[Campbell IT 4]

Hello,

We currently have Mail Security for Exchange version 4.5.10023 on our Exchange 2013 servers. Do I need to uninstall version 4.5.10023 first, or can I install 7.0.10022.0 over the top and have it automatically uninstall the old version?

Thanks.

I would strongly recommend uninstalling v4 completely, otherwise settings will be preserved which may cause issues with HIPS.
