We want to migrate from native mongoDB to Azure-hosted cosmosDB. While creating collections we see a field "shard key" which is mandatory, but currently our mongo DB set-up does not support sharding. Is it possible to migrate to cosmos without enabling sharding and with only minimal changes in our application?

Yes, it's possible. Option is right there in the portal when provisioning a new collection.
I guess the cosmos UI behaves weirdly. When I try to create a new collection by clicking on the ellipses button on a DB or choose existing DB, it doesn't provide the option to create collection without supplying shard key.
When I create a new collection and choose to create a new DB then and there, and choose not to have a shared throughput, in that case only I get the option to create collection without sharding.
