Question concerning migration on LTM
Hello,
I would like to have your advice concerning F5 migration (and more precisly migration from old F5 hardware to new F5 hardware).
I thought about different method of migration:
- One shot migration (tested without problem).
- Migration with modification from old VIP to new range and modification on client side or DNS (tested without problem).
I have thought of a third method (the architecture is organized around "one arm architecture" and auto-map SNAT):
- I keep all of my VIP address on the new architecture as on my old F5.
- I desactivate VS address on all VIP, desactivate ARP and ICMP echo.
- I connect the new architecture in parallel as the old.
=> As a consequence both architecture are in production, only the old F5 respond to VIP request (because ARP and ICMP echo are desactivate on new architecture).
=> When I want to migrate a VIP I just have to do:
- On old architecture desactivate VS address + ARP and ICMP echo.
- On new architecture activate VS address + ARP and ICMP echo.
Some of you have already have done this method? Do you think this method can work or have impact?
Thank you for your advice.
M.
