Steve and Alexander,
Thanks so much for your help on this. I will be engaging a local Juniper partner to assist with this transition. I work on our Juniper switch infrastructure quite a bit but know when to call in assistance from someone who has several Juniper certifications and works on their gear a lot more than I do. I still like to have a clear understanding of the transition process and you have provided that. Of course, once the consultant is finished and we are running on the EX4600 stack the week to week work will fall to me and my team. I will report back down the road once we have the new stack in production
Dave
