MiVB 8 to 10 upgrade path

[Dogbreath]

The Migration Guidelines for 10.1 don't explicitly say, but I am inferring that it is possible to go from 8.0 to 10.1 without passing through 9.x on the way. Is that correct?

Look at the release notes for 10.0 and 10.1.

You can go from MiVB 8.0 to MiVB 10.0 but not straight to 10.1. You need to upgrade to a version lower than 10.1 first.

10.0 Release Notes
1.   For upgrades from pre-MiVB 9.0, migration tool must be used for software upgrade to MIVB 9.0 up to MiVB 10.0 SP2.

10.1 Release Notes
1.   For upgrades from MiVB 8.0 or less, migration tool must be used for MiVB 9.0 or higher upgrade. Note: Migration is not supported to MiVB 10.1. Migrations must be completed to pre 10.1 and then upgraded to 10.1.

You have to use the Migration Tool to go from 8.1 to 9.0 first, then you can upgrade to whatever...

The OS has to to be upgraded to upgraded to Linux going from 8 to 9 and the partitions reformatted and boot code changes completely... it's changes a ton of stuff under the hood, it's all automated but takes some time.

There is no way to go to any version above 9 from any version below 9 directly, you must go to 9 first.

10.1 Release Notes
1.   For upgrades from MiVB 8.0 or less, migration tool must be used for MiVB 9.0 or higher upgrade. Note: Migration is not supported to MiVB 10.1. Migrations must be completed to pre 10.1 and then upgraded to 10.1.

That explains why there is no Migration Tool download for 10.1 but there is for 10.0.
