Hi,
Let's say you have to migrate L3 device. We all know preparation for this can be very cumbersome to do. I would like to hear your experiences, including:
1. What is your thought process when you have to prepare for migration?
2. How do you approach the pre-migration analysis? More specifically, what is that your are looking for (interface configuration, L2/L3, routing protocols, routing table, next-hops...) and in which order?
3. How do you systematize the collected data, and what tool do you use (Notepad, Excel...)?
Thanks in advance.
