We brought over ticketing data from OvationTix when we made the switch to Tessitura... sort of. None of these past events are built out in Tessitura--it is essentially just a flat file of all the events each patron attended that lives in their ticket history window on their profile. How have folks who've done this dealt with it when it comes to segmentation? We've added attributes based on historical event attendance, but are not sure what else to do since there is no way to categorize these chunks of events other than date, time, name, and how much the person paid.
When I went through implementation we made lists of different segments we might need. You could do this by writing a SQL query against the ticket history table. Then just save it as a list of all Carmen buyers in 17-18 season.
You could also import a list if you have the Tessitura constituent ID's in a CSV file, and have different segments you might need saved as a list.
