Upgrade and downgrade Splunk DB Connect

Upgrade from version 2 to DB Connect version 3.10.0 or higher

Due to changes introduced in Splunk DB Connect version 3.10.0 and higher, you cannot migrate directly from Splunk DB Connect 2 to versions 3.10.0 and higher. To migrate from DB Connect 2, migrate to a version of DB Connect 3 first (versions 3.0.0 to 3.9.0) and then upgrade to a higher version. Find migration instructions to version 3.9.0 in the previous version of this documentation.

Downgrade from DB Connect version 3.14.0 or higher to DB Connect version 3.13.0 or lower

1. Open $SPLUNK_HOME/etc/apps/splunk_app_db_connect/local/dbx-migration.conf in edit mode.
2. Go to the [encryption] stanza and change downgrade from NONE to PENDING.
3. Restart Splunk DB Connect.
