In addition, I read a few migration guide, I see everyone mention backup and restore etc but I dont see anyone mention any step about make connect between OTRS application and database, any suggest about how the connection is happened?
Thanks in advance

for the migration please just follow the official guideline. Never restore an old backup to the newly migrated system as it will destroy the installation.

For the database settings, please check the Kernel/Config.pm file of your OTRS installation
