I have a server (SLES) with UA and HPD installed (so by definition fully
patched, as you cannot get those working without all current patches),
and trying to change the IP.

I went into configupdate.sh and changed all the IP references.

I noticed this changed all the aquamarine.conf file references.

/etc/hosts has DNS name for the server changed to the new IP.

I remade my keystore for OSP with a CN=newIPaddress.

Rebooted, and no joy.

I was looking through the docs for notes on what else must need to be
done, but cannot find it.

Any thoughts?
