Export Import Database in D365 Finance and Operation across Tiers

when there is a need to move the Data across environments for Dynamics 365 Finance and Operation.
in general we will get Prod, Sandbox: Test and Sandbox:Dev env when we subscribe D365F&O.

Moving Database from Sandbox: Test to Prod or vicevarsa is fine using LCS.
but moving Database from Sandbox: Test to Sandbox: Dev or viceversa is challenging.

cause : BIG NOTE: Move Database is only available on Tier 2+ environments.

Then how if there is a case we need to move from Dev to Test and vice versa.

below are the link to do so.....

Move from Dev to Test (UAT)

https://docs.microsoft.com/en-us/dynamics365/unified-operations/dev-itpro/database/dbmovement-scenario-goldenconfig#export-the-database-from-sql-server 

Move from Test (UAT) to Dev 

https://docs.microsoft.com/en-us/dynamics365/unified-operations/dev-itpro/database/copy-operations-database 

All the steps (mainly some scripts) in above did not work for me. i did some modifications and get it done.

Do let me know if need any help.
