Move word template between instances

Hello,

It seems to have a problem with moving a word templates between instance

Trying to move a solution of custom entity from dev to test, it seems to get the wrong entitycode and connect it to a wrong custom entity,

When trying to do so using GitHub's XRMtoolbox i get the message 'memory stream is not expandable'

I saw many threads about it, did someone succeed to over come this issue?

Thanks,
Ofer
