Windchill 9.0 on HPUX 11i v3?

We have Windchill 9.0 M030 running on HPUX 11i v2 as per the software compatibility matrix. As we are planning for WC10, the requirement is for 11i v3. I'm looking for anything I can do ahead of time so that I don't have to do it on the upgrade weekend. Does anyone have 9.x running on HPUX 11i v3 and having any issues? Thanks.

Joe
