 7. `./gradlew integTest -Dtests.rest.cluster=localhost:9200 -Dtests.cluster=localhost:9200 -Dtests.clustername="docker-cluster" -Dhttps=true -Duser=admin -Dpassword=admin` launches integration tests against a local cluster and run tests with security. Detail steps: (1)download OpenSearch tarball to local and install by running `opensearch-tar-install.sh`; (2)build ML plugin zip with your change and install ML plugin zip; (3)restart local test cluster; (4) run this gradle command to test.  
 8. `./gradlew spotlessApply` formats code. And/or import formatting rules in `.eclipseformat.xml` with IDE.
+9. `./gradlew adBwcCluster#mixedClusterTask -Dtests.security.manager=false` launches a cluster with three nodes of bwc version of OpenSearch with anomaly-detection and job-scheduler and tests backwards compatibility by upgrading one of the nodes with the current version of OpenSearch with anomaly-detection and job-scheduler creating a mixed cluster.
+10. `./gradlew adBwcCluster#rollingUpgradeClusterTask -Dtests.security.manager=false` launches a cluster with three nodes of bwc version of OpenSearch with anomaly-detection and job-scheduler and tests backwards compatibility by performing rolling upgrade of each node with the current version of OpenSearch with anomaly-detection and job-scheduler.
+11. `./gradlew adBwcCluster#fullRestartClusterTask -Dtests.security.manager=false` launches a cluster with three nodes of bwc version of OpenSearch with anomaly-detection and job-scheduler and tests backwards compatibility by performing a full restart on the cluster upgrading all the nodes with the current version of OpenSearch with anomaly-detection and job-scheduler.
+12. `./gradlew bwcTestSuite -Dtests.security.manager=false` runs all the above bwc tests combined.
 
 When launching a cluster using one of the above commands logs are placed in `/build/cluster/run node0/opensearch-<version>/logs`. Though the logs are teed to the console, in practices it's best to check the actual log file.
