A Palo Alto Networks Engineer, Susmitha, shared some details about her experience using the Migration Tool.
I did a Checkpoint migration recently for a customer, and the Migration Tool 3.0 made the job much easier.
I was able to load the config into the tool, and make several changes per the customer's requirements. The NATs were migrated correctly, without any issues. I was able to connect the customer's Panorama and push API calls through the tool.
There are lot of cool new features included in the Migration Tool 3.0, such as a feature to fix the address groups with more than 500 address objects, merging configs, multi-edit, and the ability to merge several configs into one, to name a few.
An important thing to remember is to upgrade the tool before you use it. There are several changes being made and the updates are pushed very frequently.
