what's the reason behind closing your NS account? Are you migrating to a new system?Anyways, closing a NS account means your data doesn't disappear right away. It's like when you move out of a house your stuff doesn't vanish instantly. netsuite keeps your data around for a while after you close your account. If you've used the DA Warehouse for reporting and storing historical data, that info might still be available even after your main account is closed. It's like having a separate storage unit for your older stuff.
the specific details about how long NetSuite keeps your data and how to access it after closure vary based on your agreement. i'd recommend to check with your account manager for the exact scoop on your data's afterlife...
