SLP Side by Side

Hello,
I have a production SMS 2003 environment that's working well.  I have recently created a completely seperate SCCM server with a different Site Code and plan to move clients and secondaries over, one boundary at a time.

My question:  Should I not create a Server Locator Point role on the new SCCM server to avoid confusing clients?

It's important that while I'm building/testing the SCCM environment I not accidentally disrupt the SMS 2003 environment.  I know to avoid overlapping boundaries and naming the primary Site codes the same.  Are there any other gotchas?

Thank you,
