I'm needing to move the management of our firewalls from an on premise server to AWS. I thought the easiest way to do this would be to build a new manager in AWS and join that as a Management HA node, however the AWS version of the manager (from the marketplace) is a differing version so I cannot create the HA. We have R81.10 take 335 on prem and the new AWS one is R81-392.1335. I can't seem to find a way to deploy R81.10 take 335 in AWS.
Is it possible to use the AWS Application Migration tool on the manager to replicate it up to AWS, but then not do a 'cutover' thus effectively duplicating the server, reset it's SIC, then join it in to the existing on premise management?
Is there some other, better way to achieve this? The ultimate goal is to move the management to AWS and use that to manage our on prem devices, preferably without doing a migrate_export to the new server and then moving the firewalls across to the new manager one at the time.
thanks Matt
