Database migration

[satish]

Dear erman,

We are planning to migrate 11.2.0.1 database using expdp to new server having 12.2 version using network_link option.

Our db is 120Gb

Do we need to shut down our java application during this migration?
Not to make any changes to the source as we are migrating to new server?

Pls suggest

Thank you

Ofcourse, if your application is changing the data stored in database, then you need to stop it.
But there are some other solutions which can be implemented , but those solutions are applicable to some specific cases.

However;  as your question is super general and generic, my answer is yes.
