Hi team,
We have been planning to upgrade our Neo4j server from v3.5 to the latest stable version.
Can anyone help me by providing few links or providing few documents which could help me as developer to understand what all step i need to take on the existing code base and configurations so that its easy for us to migrate and upgrade our code and configs.
Also can we directly migrate from v3.5 to v5.X !!
Something similar was recently asked. @dana_canzano responded with some references. See if they help.
Here is the previous post.
Here are my suggestions:
Step 1: simply copy the graph.db folder.
Step 2: Go to 4.3 or any higher version
Step 3: Paste the folder from Step 2 in data/databases folder of Step 2.
Step 4: Open the terminal (from Step 3) and run this:
bin/neo4j-admin copy --from-database=graph.db --to-database=graphdb --force
(select any name for to-database)
Step 5: Once step 5 is successful, then run in Terminal:
bin/neo4j-admin store-info data/databases/graphdb (replace graphdb with the correct name)
Result should show:Store format version: SF4.3.0
Store format introduced in: 4.3.0
Once all the above steps are completed, copy the graphdb folder from data/databases (as in Step 5).
Step 6: Paste the copied db folder in V5.5 or above data/databases folder.
Final Step: Open Terminal and run this: bin/neo4j-admin database copy graphdb graphdb5 --force
Final Check: In Terminal run this:bin/neo4j-admin database info graphdb5 (use the correct name)
Result should show you format version 5 info.
That's all!
