AltostratusDear Paulius
Many thanks for your response,
You mentioned that "options are a bit limited" could you please advise about a different procedure if config migration is not the best.

Thank you,

AboAmir Typically the better option to drastically reduce downtime is to standup the new F5s with the same configuration but just different IPs. Typically this isn't a feasible option because of limited IP space but is the better option because it allows you to allocate all new IP addresses and migrate virtual servers one at a time and then once everything has been tested, assuming your F5s are in path you can reroute the larger subnet to them and then remove any /32 routes you put in place for testing purposes. Going this route allows for near zero downtime assuming the VSs and routing that you are testing work when you put the temporary /32 routes in place.
