Can I use SQL commands to import legacy data into the database?
Importing data in any fashion other than through the Import menu is highly discouraged. Using SQL commands to populate the database is especially fraught with problems and support cannot be guaranteed if that import method is chosen.
The AT API may be used to import legacy data, however the API is in fairly rough form at the moment and this type of import has not been tested. The AT technical staff may be able to assist with import for a negotiated fee.
