I initially set up my Odoo instance with USD as the base currency and have been using it for some time. Later, I enabled multi-currency support and added PKR as a secondary currency.

Now, I have some data in PKR and Some in USD. I want to completely switch from USD to PKR — meaning I want all existing records, historical transactions, journal entries, sales/purchase orders, and reports to reflect PKR instead of USD. Going forward, I also want PKR to be the only currency used across the entire system, including all future transactions and reporting.

What is the best way to achieve this in Odoo? Is there a proper migration path, or would I need a script to update all monetary fields and currency settings? Also, how can I ensure consistency in financial reports after the conversion?

Any guidance or best practices would be highly appreciated.
