New Chart of Accounts for an existing Company

SOLVED

I created our registered charity in SAGE but I skipped the step to import or use the default chart of accounts when using the Wizard.

Now it appears that I have to create every account individually

or create a new company to be able to use the Wizard.

I cannot find a way to set up the default chart of accounts or

find detailed help to import my old chart of accounts from our previous system. (I know this is going to be difficult)

Can you suggest how to proceed?
