Symantec System Recovery 2013 and Repartitioning

I have the usual problem of a Raid 5 with a too small system drive partition that I need to extend without it corrupting data on the other partitions.

Was going to buy Partition Magic but now this has been replaced by Norton Ghost which has now been replaced by Symantect System Recovery 2013 (or so Symantec website says)

However, both Symantec's Customer and Technical support lines could not help - so can someone with the product let me know if this tool can repartition Raid 5?

Thanks for the help!

Cheers

Paul
