How to Migrate HA Netscaler node from Xen to Vmware HyperVisor
Hi All
Please find the tested scenario for how to migrate the NetSCaler VPX from Xen to Vmware HyperVisor.
There is 2 node of NS in HA mode. 1st node X (primary) and another node Y (Secondary).
Action for X node:-
1. Login to Primary X
2. goto HA settings --> Select Primary node -->select Stay primary and select stay primary when another node is unstable
3. click on the Secondary node Y --> Select stay secondary
Action for Y Node:- we will migrate the Y node to Vmware solution.
1. Login to Server via SFTP
2. Take the backup of NSconfig folder
3. note down the IP Address
4. take the snapshot
5. Break HA
6. Down the Y node on XenServer
7. Powerup the Node on Vmware new one
8. configure the IP Address
9. Connect via SFTP
10. overwrite the Nsconfig folder data from old NS device
11. Reboot the NS device
12. upgrade the license file with the new hostname
13. All Reboot
14. All the settings will be same as the old node
15. verify the configuration
16. ADD to HA
17. configure the normal HA settings
18. do the load failover and testing
All will work as normal and perform the same action for X node then.
Action for Y node:-
1. Login to Primary Y
2. goto HA settings --> Select Primary node -->select Stay primary and select stay primary when another node is unstable
3. click on the Secondary node X --> Select stay secondary
Action for X Node:- we will migrate the X node to Vmware solution.
1. Login to Server via SFTP
2. Take the backup of NSconfig folder
3. note down the IP Address
4. take the snapshot
5. Break HA
6. Down the X node on XenServer
7. Powerup the Node on Vmware new one
8. configure the IP Address
9. Connect via SFTP
10. overwrite the Nsconfig folder data from old NS device
11. Reboot the NS device
12. upgrade the license file with the new hostname
