Upgrading to ArangoDB 3.2
|
|
=========================
|
|
|
|
Please read the following sections if you upgrade from a previous
|
|
version to ArangoDB 3.2. Also, please, be sure that you have checked the list
|
|
of [incompatible changes in 3.2](../../ReleaseNotes/UpgradingChanges32.md) before
|
|
upgrading.
|
|
|
|
Switching the storage engine
|
|
----------------------------
|
|
|
|
In order to use a different storage engine with an existing data directory,
|
|
it is required to first create a logical backup of the data using *arangodump*.
|
|
That backup should be created before the upgrade to 3.2.
|
|
|
|
After that, the ArangoDB installation can be upgraded and stopped. The server
|
|
should then be restarted with the desired storage engine selected (this can be
|
|
done by setting the option *--server.storage-engine*) and using a non-existing
|
|
data directory. This will start the server with the selected storage engine
|
|
but with no data.
|
|
|
|
When the server is up and running, the data from the logical backup can be
|
|
re-imported using *arangorestore*.
