Currently I am working in Sitecore upgrade 8.2 to Sitecore 9.3 also upgrading Sitecore 8.2 analytics code to Xconnect. Now I have some doubts in xDB data migration.

We already have our xDB setup on Mongo 3.6 Atlas PAAS for Sitecore 8.2. I would like to understand how to migrate xDB data which is available in MongoDB atlas 3.6 to Mongo 4.0.5 mongo atlas which we are going to use for Sitecore 9.3. Is it possible to use xDB migration tool ?

Could someone please suggest how to migrate xDB data from mongo atlas 3.6 to mongo atlas 4.0.5.
