change node types

Hi,

I've created a custom name space and some node types with the super type mix:versionable. Having mix:versionable as a super type is not a good idea, because all nodes of this type will get a version history at their creation which costs repository space and write performance (the better solution would be to add mix:versionable if needed).

Now I want to change the node type and can't find a proper solution to do so. Removing the mix:versionable super type is a major change (NodeTypeDefDiff), which is reasonable cause the existing nodes do know about mix:versionable only about their primary node type. Rebuilding the complete repository isn't an option either.
If I register a completely new node type, then I have to consider this in all queries like "Select * from nt:base where jcr:primaryType = 'myApp:nodeType' or jcr:primaryType = 'myApp:newNodeType'.

Is their a better solution for this, like adding a common node type as super type for both the new and the old node type? (which don't seem to work)

Kind regards, Robert

Mit freundlichen Grüßen

Robert:

Is Node.removeMixin("mix:versionable") of any use to you for this problem?
