>
> Each time a version history is copied during the upgrade, the copier tool has 
> to traverse /jcr:system/jcr:versionStorage ancestors to get the appropriate 
> nt:versionHistory node. It can be optimized by reading the versionStorage 
> node once and re-using it. As a result, all methods related to copying 
> versions should accept versionStorage rather than rootNode as their 
> parameters.
