/testrunner i ubuntu_x6436_01-XDCR_upgrade-P1.ini get-cbcollect-info=True,get-logs=False,stop-on-failure=False,get-coredumps=True,upgrade_version=3.0.0-973-rel,initial_vbuckets=1024 -t xdcr.upgradeXDCR.UpgradeTests.incremental_offline_upgrade,initial_version=2.0.1-170-rel,sdata=False,bucket_topology=default:1>2;bucket0:1><2,upgrade_seq=src><dest

[Test Steps]
1, Installed Source (2 node) and Destination node(2 node) with 2.0.1-170-rel.
2. Change XDCR global settings: xdcrFailureRestartInterval=1, xdcrCheckpointInterval=60 on both cluster.
3. Setup Remote clusters (Bidirectional).

bucket0 <-> bucket0 (Bi-directional) 10.3.3.240 <--> 10.3.3.239
default ---> default (Uni-directional) 10.3.3.240 -----> 10.3.3.239

4. Load 1000 items on each bucket on Source cluster.
5. Load 1000 items on bucket0 on destination cluster.
6. Wait for replication to finish.
7. Offline Upgrade each node one by one to 3.0.0-973 along with load 1000 items on bucket0 and default at Source cluster.
8. Verify items on side.

Expected items on bucket0 - 6000 and default = 5000
