Migrate application from service guard to standalone non clustered server

All

I am working on a project to migrate the applications from service guard cluster to a standalone third server( non clustered VSOE ) node.  The storage has been already zoned to the new server.  Following are the steps I came up with to accomplish the tasks.

 

I need to also delete the packages and cluster on the source cluster post migration.

 

SG nodes: A(primary),B(standby)

New server : C

 

On server A:

 

1) halt all packages

2) vgchange -c n <each vg>  ( is this neccessary ?)

3) Create map files for each VG and scp to C

4) On C, import VGs, create mount point, fstab entries and mount file systems

5) Turn over to application admin

 

Do you see any issues with above steps? In between 2 & 3 do I need to manually import VGs on A first?

Also I need to delete the cluster, packages on A,B.  How can I accomplish this without causing any impact to C

 

Thanks in advance
