Hello Randi Sue,
From a Support prospective, we do have customers that ask about this from time to time. In the event that you need to preserve the data is the period that it occurred, for tax reasons, you may want to consider creating a new company.
In order to "transfer" the information, you can export the journal entries via the Import/Export Utility (Export Tab) Change the Company and Property ID to the "New" company and then re-import via the Import/Export Utility (Import Tab). If you would like more details please feel free to open a case with our support team and we will assist further.
