items lost after doing an offline upgrade of a cluster which has xdcr replication stream to another 2.0 cluster

Scenario:

• 5:5 ec2 node ubuntu 12.04 clusters
• Hostnames used, ip file updated with hostname
• biXDCR_bucket: C1 <---> C2
• uniXDCR: C1 ----> C2
• Load about a million items on both buckets at C1, and another million items on just the biXDCR_bucket on C2
• Initiate offline upgrade on C1 (from 2.0 to 2.0.1)
• Stop all nodes on C1.
• Manually upgrade the cluster (dpkg -i couchbase-server... )
• Upgrade completes, buckets recreated, however items not loaded
• Also XDCR replications not retrieved.

The live cluster:
C1: http://ec2-177-71-230-72.sa-east-1.compute.amazonaws.com:8091/
C2: http://ec2-175-41-186-167.ap-southeast-1.compute.amazonaws.com:8091/

Access:
ssh -i SanPauloQAKey.pem ubuntu@ec2-177-71-230-72.sa-east-1.compute.amazonaws.com
ssh -i SingaporeQAkey.pem ubuntu@ec2-175-41-186-167.ap-southeast-1.compute.amazonaws.com

The items seen on biXDCR_bucket in C1, are those that were replicated from C2 to C1 after the upgrade of C1.
