The Actify development team adjusted and verified Centro on ArangoDB 3.8.x. Actify recommends using fully supported versions of ArangoDB.
According to ArangoDB, as ArangoDB 3.8 is available support for ArangoDB 3.7 will end around May, 2022. (https://www.arangodb.com/subscriptions/end-of-life-notice/ )
As of August 31, 2021, support for ArangoDB 3.6 has ended.
Upgrading your organization's Centro system to ArangoDB 3.8.x typically goes without incident. To minimize potential issues
Backup database data
Endpoint configuration files
Backup other system data especially if one's database is on the same system as the Centro installation such as
