Recently inherited a 2.1.4 install of neo and looking to upgrade to latest greatest. It appears that I need to move it stepwise through the 2.x versions before I can get to 3.x though.
Have taken a copy of the existing "graph.db" folder and am trying to bring it up in 2.3.1. The following error code appears when I start (with "allow_store_upgrade=true"):
<path>/neostore.nodestore.db' has a store version number that we cannot upgrade from. Expected 'v0.A.3' but file is version ''.
The backup was taken from the current working system by:
- shut down
- tar -cfz graph.db.tgz <graph.db path>
- Is it not possible to go from 2.1.x to 2.3.x? Do I need to find 2.2.x first?
- Is there a different / better way to backup / restore the data?
- Is this the appropriate upgrade path (2.1 -> 2.3 -> 3.1?->3.5?)
