regarding the "If You’ve Ever Had OES 1 Linux Servers with LUM and NSS Installed" caveat in the planning and implementation guide located here:

Novell Doc: OES 2 SP2: Planning and Implementation Guide - Caveats to Consider Before You Install

I'm about to install a new OES2SP2 into a existing single server TREE running OES1SP2. Now I'm wondering which of the provided solutions covers my environment? Is it the fix_xtier_ids.sh solution I should do on the existing OES1SP2 box before installing OES2SP2 into a different context than where my OES1SP2 server resides?
