Hello!
> Two Exchange 2010 SP3 RU23 Edge Transport servers at DMZ installed with DKIMx 1.20.120 version
> We are planning to upgrade our Exchange Servers from 2010 to 2016.
> What is best method to upgrade to Exchange 2016 along with DKIMx ?
After you installed MS Exchange Server 2016, install DkimX 3.20 and then perform the following steps to migrate the configuration of your previous DkimX 1.20 installations:
1. Stop the DkimX Management service.
2. Delete all existing configuration files in the directory <InstallDir>\Data\Configuration.
3. Copy the old configuration file Config.xml into the directory <InstallDir>\Data\Configuration.
4. Start the DkimX Management service.
