Step1: Database Backup
Recommended to migrate in Test instance initially
Stop the previous version of Grafana running on the instance and change the start type as Manual
Follow the below steps to backup existing database
Navigate to <postgres_installation_path>/bin
Backup DB by executing the command pg_dump --username=username --password grafana > grafana_backup
Stop the previous version of Grafana running on the instance
Follow the below steps to backup existing database
Login as postgres user su - postgres
Backup DB by executing the command pg_dump --username=username --password grafana > grafana_backup
DB Restore
Drop all schema
Login to postgres DB and execute below commands
psql -U grafana
\c grafana
DROP SCHEMA public cascade;
CREATE SCHEMA public;
Restore the default grants
To restore defaults grant execute the below commands
GRANT ALL ON SCHEMA public TO postgres;
GRANT ALL ON SCHEMA public TO public;
Restore DB
To restore Db execute the below command
psql --username=username --password grafana < grafana_backup
Step2: Manual Backup of Dashboards
Using the “share dashboard” option from the dashboard menu, export all dashboards from each and very Org as a JSON file and save it to a physical location
Step3: Grafana default settings
Use the Grafana default settings bundled in Grafana 7.1.0 by Insights team, or make all necessary configuration changes in conf/defaults.ini as per preference.
Step4 : Start Grafana
Run ./Grafana7.sh start to start Grafana(Usage - Grafana7.sh {start|stop|restart|status}).
Run grafana-server.exe file from the bin folder of Grafana or run Grafana7-Tomcat-SetUp.bat and Grafana-Tomcat-StartUp.bat create it as a windows service as per convenience.
Step5: Grafana DataSource Renaming
Rename the existing Grafana Neo4j DataSources in all Org(For example Neo4jLocal to Neo4jLocal_old) and create a new DataSources using latest DataSource plugin Neo4j3.0
Insights now has two Neo4j DataSource plugin
Neo4j2.0 - Typescript and Angular.js based.
Neo4j3.0 - Using React Framework with Grafana in-built plugin framework
Neo4j2.0 is deprecated in Grafana 7.1.0 so it is recommended to add new DataSources using the Latest DataSource plugin Neo4j3.0
- Both these data source will work fine until Grafana 7.0.3 but any feature improvements will be added only to Neo4j3.0, since Grafana moved its source code to support react . So it is recommended to use the latest DataSource plugin Neo4j3.0 for Grafana Migration.
For a successful migration ensure to rename the existing DataSources and create new DataSources using lastest DataSource plugin Neo4j3.0, before starting the Dashboard Migration
The old Inference DataSource has been deprecated, for Grafana 7.0.3 and above use Inference_DS3.0 and inference-plugin
Enter the Http url : http://localhost:8080/PlatformService/datasource/inference/data/v7
Step6: Compatiable changes for Grafana 7.1.0
Convert the dashboard json that has been exported from Step2 into a compatible format for Grafana 7 using the below steps
Before importing the dashboards into Grafana delete the existing dashboards to avoid error “A dashboard in this folder with the same name already exists”
Grafana dashboards are backward compatible which can be exported from previous version of Grafana and imported into Grafana 7.1.0 by doing the following changes in the exported json file
There are two data formats in Grafana 7.1.0 Table and Graph(timeseries). Either of one should be selected in the datasource while querying, based on the panel preference
Export Dashboards as json file from the previous Grafana version
change the following fields inside targets array of exported json file as below and the same is depicted as table comparisons higlighting differences
“target” to “queryText”
“rawQuery” to “table”
“hide”: true to “hide”: false
Make sure that "hide": true inside annotations element is not changed to false
Exported Dashboard json file(previous Grafana Version) | Compatible changes for Grafana 7.1.0 |
|---|---|
{ } | { } |
If the panel is a graph panel then mark table as false and mark graph as true
“table: false,
”graph”: true,
Exported Dashboard json file | Compatible changes for Grafana 7.1.0 |
|---|---|
{ | { |
Singlestat and Table plugins are removed in Grafana 7.0.3 and above
Singlestat is replaced with Stat; Stat is a Grafana native plugin which has more features than Singlestat
Table plugin is replaced with Newtable plugin
Please Note Newtable plugin does not have pagination
But we have use the old SingleStat and Table plugin which is backward compatible using export and import previous Grafana Dashboard json.
