    Description

      Build
      6.0.0-1643

      Testcase
      ./testrunner -i /tmp/testexec.5266.ini -p stop-on-failure=False,get-coredumps=True,fail_on_errors=1,upgrade_version=6.0.0-1643,get-cbcollect-info=True -t xdcr.upgradeXDCR.UpgradeTests.test_backward_compatibility,initial_version=5.0.0-3519,items=50000,bucket_topology=default:1>2;standard_bucket_1:1<2;sasl_bucket_1:1><2,expires=50,checkpoint_interval=60,GROUP=BACK_COMP

      This is a regression between builds 6.0.0-1614 and 6.0.0-1643
      Steps
      1.Load 3 buckets on source cluster running 5.0.0-3519 build. (default, sasl_bucket_1, standard_bucket_1)
      2. Install 6.0.0-1643 build on destination cluster.
      3. Setup C1->C2 XDCR for default bucket, C2->C1 for standard_bucket_1, C1 <-> C2 for sasl_bucket
      4.Perform replication verification on source-target. Verification fails only for standard_bucket_1. (0% replication in 300s)
