Yes, I was previously on 11.0.5 with Office 2010. I've since upgraded to RU6MP2 but I didn't have any issues. I'm not an Office power user by any means. Mostly Excel and Word but was able to copy and move files around without issue.
Word/Excel both seemed to open relatively quickly. You may want to test first before upgrading but from my personal view, all was and still is working fine.
