Impact on Inventory - Change in Zoho Migration Date

Impact on Inventory - Change in Zoho Migration Date

Hi, 

I want to prepone my zoho migration date from July'2025 to April'2025. Before I do so I want to know what will happen to my inventory opening balance when I change the migration date? And how can I change the inventory opening balance? Currently I cannot change the figure in the opening balances page.

Also are there any other best practices to follow while changing the migration date that I should be aware of?
