Manually Updating Multiple Databases
When updating to Abacus 2015, your data01 database (which is the main database) is automatically updated from the v22\data01 folder to the Abacus\v23 folder.
However, if you use multiple databases, databases other than data01 are NOT automatically updated. To update databases other than data01 manually, run Abacus 2015 using data01. Then, for each database other than data01, select File > New database and create a new folder under v23 and specify which v22 folder to use as the source.
