Description:
Upgrading from 6.3.x to 7.0.6 ndbmtd makes the cluster crash instead of a warning that this is not allowed.

How to repeat:
Upgrade 6.3.x directly to 7.0.x ndbmtd.

Suggested fix:
Jonas states:

>> You must first upgrade to single-threaded ndbd, before changing to multi-threaded ndbmtd.
>>
>> i.e upgrade cluster 6.3.20 -> 7.0.6 ndbd
>>     upgrade 7.0.6 ndbd -> 7.0.6 ndbmtd
>>
>> the fact that we don't return a informative error message is also a bug
>> that should be reported.

Jon: Please make sure that documentation states that this is not supported

Hi guys,

The idea of this bug was NOT to fix the docu (what Jon already did "long" ago). The idea was: See initial description!

Please open a new *Server* bug and assign it to a *developer*.

This *Documentation* bug has been fixed and closed!

Thanks!
