Post Activity, Back Up Existing Data, Purge, and Reindex
You must post all transactions and activity before you convert. If you have open batches in Payroll or Bank Reconciliation, you must post or clear them before you convert.
It is critical that you back up your existing data. Although it is not likely, if something unforeseen occurs during the conversion process to corrupt your data, you can restore it from the backup.
If you have a large amount of data, the conversion process could be lengthy. To decrease the conversion process time, we recommend you purge unneeded data from each module you convert; always back up your data before you purge it.
You should also reindex your data files before you convert your data to Denali. This checks your files for corrupt records.
When you finish all of the recommended preparation processes, continue to Conversion Process.
