We have a client who has 2 RE accounts. The default RE account (in company profile) was setup (or changed) and is currently classified as a balance sheet account. The second which is used to close out a few departments is/was correctly classifed. They wish to change the default RE account classification, but before making the changes would like to know what problems if any this may cause.

Of course we'll ensure that all data is backed up prior to any changes. The system warns or possible problems with Year/End + balancing. Other than backups what should be known or done prior to proceeding?
