symantec backup exec 2010 R2 license renewal

hi

I have symantec backup exec 2010 R2 and my license expires on 31 May 2014. Every year I renew my license through a local vendor. However, this year when I contacted the vendor they are saying it is not possible to renew the license for 2010. I was asked to upgrade it to 2012. Hence, can any one update me on this.

Thanks
