vmware alternate restore from BE2010 to BE2012 environment

Hi All,

As subject above, I have few concerns since I'm not able to perform alternate restore on the vmware:

1. Production running BE2010 while DR running BE2012. Can I perform alternate restore since the ver is different? Do I need to perform cataloging/import the image from tape?

2. The production backup using vcenter to backup while the DR use ESX to perform the backup. Since the backup method is different, does the alternate restore is doable at DR site?

3. The restore button/option is blur and I'm not able to hit/click on it, seems is the option is not enable for the ESX machine. How I gonna perform the restore?

Thanks in advance.
