How much application downtime I can expect if I want to migrate Cassandra to AMAZON KEYSPACES?

Question

I want to migrate my 3-node Cassandra cluster containing 150GB of data onto Amazon keyspaces.

How much application downtime can I expect and what is the procedure for migration which will take minimal application downtime?

Edited:

I have looked into the AWS article they have provided 4 approaches. https://docs.aws.amazon.com/keyspaces/latest/devguide/migrating.html

I'm thinking to go with the DataStax Bulk Loader approach. Can anyone please tell me how much application downtime will this approach take?

@priyankchopra you may want to check this page out to see if you wanted to migrate to a serverless DBaaS that is fully compatible with Apache Cassandra™ which comes with a Zero Downtime Migration option. Here is [one] a customer experience.
