Hi,

We are working on supplier data migration as part of new implementation project. Supplier volume is around 1000 suppliers. Each supplier contains on an average of 10 attachments which translates to 10000 attachment approximately for all the suppliers. We would like to understand the below.

1. I believe all these attachments will be stored in UCM. If yes, will there be any storage constraint to consider?
2. Will there be any impact on the system performance if we import such large volume of attachments?
