Handling Serial Number Mismatch After Data Migration in ERPNext

I recently migrated 5 years of data, including serial numbers, into ERPNext. However, I noticed that the serial numbers do not match the opening stock.

To manage this, I plan to disable the migrated warehouse and treat all opening stocks as new stock entries. Instead of modifying the existing serial numbers, I want to add a specific keyword or prefix to the serial numbers of new stock entries to differentiate them from the migrated ones.

Additionally, this keyword will help prevent serial number duplication issues between migrated and newly created stock.

Would this approach work without affecting stock transactions and reports? Is there a recommended way to implement this while maintaining data integrity?
