Upgrading from an Earlier Version of Sage 50 Accounting
If you want to use company files from an earlier version or release of Sage 50 Accounting or another accounting program, you must upgrade your data into a format that works with the current release of Sage 50 Accounting.
Before attempting this, be sure the totals of your accounts are the same as the totals of the corresponding subsidiary modules. For example, make sure that the total of all balances owed to your vendors is the same as the balance of the Accounts Payable account. Do not upgrade your data until all the accounts balance.
We recommend that you back up your company data before upgrading.
