SQL_CANTOPEN diuring vmware conversion ?

When converting a VM I came across this error about 2/3rds of the way through the conversion.  The vm was an OVF on a local disk with a target on a remote esx. In this case it was worth checking that any antivirus is off temporarily and that any backup related software is closed. In this case Carbonite, Crashplan and other similar packages including Virgin’s own backup tools are candidates that start in the background. After identifying one that fitted into the category and stopped it. The conversion ran fine so worth looking out for if running a coversion that fails with that error.
