Upgrade and downgrade Splunk DB Connect

How to upgrade Splunk DB Connect

Throughout its lifecycle, DB Connect has adapted to changes in architecture and functionality. Splunk provides migration logic to make these updates as easy as possible. However, for simplicity and to reduce the time spent on maintenance and implementation of migrations, in some cases it is not possible to migrate from one version to another. Splunk recommends reviewing the table described below to help with the upgrade process.

Upgrade paths to version 4.x.x

Please review the following table carefully to choose the right migration path for your case. Not shown are some of the versions that have actually introduced major disruptive changes, those versions are: 3.10.0 and 3.14.0

Current version	First upgrade	Second upgrade	Latest available	Release notes
2.x.x	3.9.0	3.18.0	4.x.x	3.9.0 3.18.0
3.x.x	3.18.0	4.x.x		3.18.0

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.
