We have a SQL 2008 active passive cluster. i'm about to upgrade it to 2012. i've done days worth of research and have everything I need including prerequisites and validations etc. One thing though, MSDTC is installed but not clustered yet. I can't cluster it because I don't have a disk on the iscsi md300 available in time.
Is a clustered MSDTC required for a SQL upgrade?
Also, does anyone know the disk space requirement for clustering MSDTC?
Thanks,
