Hi Dragan,
Just to confirm what's stated above: you should be fine. Read the Best Practices Document so that you will know exactly what to expect.
I do recommend upgrading to Release Update 6 Maintenance Patch 1 (RU6 MP1). It contains an important improvement:
Citrix causes SMC start failure
Fix ID: 1914056
Symptom: SMC and COM+ Event System services do not start when Symantec Endpoint Protection is installed with Citrix PVS Device software.
Solution: The Symantec Endpoint Protection client was modified to allow SMC to start when installed with Citrix.
Full details can be found in http://www.symantec.com/docs/TECH103087
Thanks and Best regards,
Mick
