My company is in the process of upgrading our current version of GMG (4.5) to 5.1. The interface looks quite different than what I'm used to seeing with 4.5. My question is: do you think the upgrade is pretty easy to learn or would it be advisable to get in-house training? Would the application tech support be able to walk me through in the creation of the MX3/MX4 profiles over the phone? The bottom line is we are not sure whether we should pay for the in-house training or not. If I already understand 4.5, is the new version so much different?
