If a customer decided to keep the IO data after IO license stops:
1/ When the feed ends the data will remain within Fastrak (Static - Except for re-occurring flows which have a start and end date, these will continue to create transactions until they hit the end date).
2/ Any IO policies (Where source is IO) with investments etc... will remain the same and will not update (All updates will need to be done manually). This includes non-platform assets that will need to be added manually there is no option to put these on in bulk.
The IO data maybe ok for the first few weeks as the data will still be fairly accurate but over time it would eventually become less reliable as the data changes.
Recommendations would be to remove IO data and rely on satellites
