I can't get that article to come up, but I assume it's the one saying you need to upgrade from
netsuite.com to
netsuite2.com? Assuming so, there might be a fair amount to do, depending on how extensively you use data from ODBC.
Most table names and most field names, and the overall table structure is significantly different in NS2 vs NS1. Assuming you have tools hooked up to ODBC like Power BI, Tableau, or some data warehouse, you might have to make a bunch of changes.
Basically if you have a bunch of custom SQL, you'll need to update that for all the new tables and field names. Even if you're doing as little as just dumping the data to a data warehouse, you'll have to set up a new connection to keep getting the data. Good luck.
