graphindex not created while migrating from titan to janus

[yzainee-zz]

We were using titan and wanted to migrate to janus. We wanted to use the same tables which were used in titan.
For this we have the following 3 configurations
config params storage.backend = com.amazon.janusgraph.diskstorage.dynamodb.DynamoDBStoreManager
storage.dynamodb.use-titan-ids= true
storage.dynamodb.stores.ids.store-name= titan_ids

But what we are observing is that instead of earlier
(titan)
edgestore
graphindex
system_properties
systemlog
titan_ids
txlog

we see
(janus)
edgestore
system_properties
titan_ids

Why dont we see the graphindex created for janus? Is there some kind of configuration that we need to set for that?

Note: We have millions of records / data which we had created using Titan. now we want to migrate from titan to janus and want to use the same data instead of creating everything from scratch.

Currently, after migrating from titan to janus, when we do a gremlin=g.V().count() we get 0. Is there any configuration that we need to set? i have paster the 3 config variables that we have used for the migration above in the issue.

config params storage.backend = com.amazon.janusgraph.diskstorage.dynamodb.DynamoDBStoreManager
storage.dynamodb.use-titan-ids= true
ids.store-name= titan_ids
graph.titan-version=1.1.0-SNAPSHOT

Have also tried these configuration.
