You can change the account number, account name, and if allowed, the account level of an existing account. (The level of the eight Level 1 accounts -- asset, liability, income, expense, capital, cost of sales, other income and other expense -- can't be changed. In addition, header accounts you create must be either Level 2 or Level 3.) When you change an account's number, the Accounts List is reordered (in account number order). If a header is separated from its sub-accounts, the sub-accounts are moved up one level.
