Hi Shai, I got access to your store and using the backed up nodestore and relationshipstore in upgrade_backup, I compared contents of the upgraded (2.1.2) store to that of the 2.0.3 store.
What I found found was that all nodes, properties and relationships are exactly the same. I dumped nodes, their properties and their relationships (and properties) to text files, sorted, for both stores and they have the same contents, down to the last character. I also did this for just the INCOMING relationships, just for the heck of it, since you observed issues with those. And the outcome is the same. Can you redo your checks for the upgraded store and provide more details about the problems?
