Yes, of course. It is actually hard to avoid when you work with AIX.

I don't know what you mean by "checkpoints". If you have used the NIM methods to create the mksysb you have already established a working communication between the NIM server and the client. If you want to restore the mksysb image to the client create a NIM resource for this client, shutdown the client, start it into the SBB menu, enter the IP address of the NIM server into the appropriate menu screens and off you go. NIM relies on bootp as a protocol, therefore all the routers, switches and whatever network equipment you have between client and server have to pass through bootp.
Further, there is a common problem with exports: NIM will create a (temporary) NFS share (/etc/exports) for the client on the server. If a superdirectory of this share is already exported this may (or may not) confuse NIM. The best way to avoid this is not to export any superdirectory of the place where the NIM resources are located.

If you run a server with HACMP this is indicative of the server being quite critical to some operation. In such a case not having tested backup and restore of the system
before commissioning it is somehow careless, isn't it? In this case you should announce some downtime with the users to test the process. It is almost 100% foolproof and rarely fails, but in the remote case of failing you will not have to explain why you're testing on a productive system.
Anyway you don't have to unmirror anything: a mksysb image is basically a "savevg rootvg" and contains not only the data of the rootvg, but also the disk layout, the filesystem layout, etc..
I hope this helps.
