Hi, Ram!
There are few variants to organize such migration.
1. Use this relatively new tool (suiitable for all cases): uds.systems/.../data-migration-tool
It was designed with a purpose to automatically migrate data from on-premise to the cloud.
Check the tutorial before using the tool. It might prevent you from common issues that usually occur:

2. Regarding the article: https://cutt.ly/DfcGZaU
If your organization has a combined annual adjusted revenue of $300,000 or more, then you will be eligible for FastTrack, and basically, Microsoft will help you to get updated and move to online directly from your current on-premise version. Of course, it could require developers' involvement from your side to solve the compatibility issue during the upgrade process with Microsoft.
3. If your organization is smaller, perhaps you might require assistance (Visit: https://uds.systems/)
Stages of the process:
- Migrate/re-create your customizations, custom code, reports, etc. to Dynamics 365 Online
- Migrate all data from the existing environment to Online (you continue using the existing system)
- During some weekend migrate delta (only changed data)
- From now you will start using a new Online environment.
I hope everything will turn out smoothly =)
And if you have already finished the migration, please share how. I am interested in your opinion on the process and results =)
