CirrusVPN SSL Users migration
Hi,
We have our F5 4000 platform that will be replaced.
we have on that platform 2000 VPN SSL users , and reverse proxy / Load balancer
I would like to have any idea for these migration.
Could we migrate all users at the same time? how can we process?
Public addresses also change for VIP how can we take in account this change.
Since new F5 will be install, could we export ucs config file and import it on the new one?
Thanks for your help and for your quick reply

Hi,
You can create a active/standby cluster of 4 BIG-IP's (old and new). Sync the configuration and do a failover to the new hardware.
Later you can remove the old hardware from the cluster.
Your users won't notice you did the failover (if the setup is done correctly).
Cheers,
Kees
MariemeHi,
Thanks for your feedback. I did not mentionned it but the new cluster is on cloud Azure.
Should we proceed the same?
Regards
Hi,
No you did not. Then I would create the new cluster, ssl vpn configuration. Test it with a small group of testers and then migrate all users to the new solution. (DNS change).
I would not use a UCS backup, I would use parts of a SCF to create the virtual servers on the Azure hosted BIG-IP's.

Thanks for this reply.
Without importing UCS, which way is the good one to import/ modify VIP configuration since pubic IP addresses change.
Regards
In Azure you can not configure a public IP on the BIG-IP. Only private IP's.
I would export the SSL VPN policy from APM. Install the same version of TMOS in Azure.
Take a SCF backup and extract the parts of the SSL VPN Virtual server. Modify the destination IP.
First import the Access Policy.
On the CLI in Azure perform a
tmsh load sys configure merge from-terminalAnd past you virtual server configuration, end with Ctrl D
