Can not Backup data in modeshape 3.7.2 due to the out of memory

[hank.cheng]

Hi All,

We need to upgrade the modeshape from 3.7.2 to 5.1.0 in our project, We try to backup the data from 3.7.2, but it fails because of the out of memory, and our java memory is 8G, our jcr data size is 400M.

Now we must upgrade the modeshape, any suggestions is welcome

THanks
