We have deployed a custom web part having custom properties can be configured by user. This is already in production.
The change : From next version we will be modifying one web part property[existing] default value.
Expected:
This property value should remain same for the web parts as users already using it for existing pages. It should affect only when adding new web part.
Problem: This is affecting for all the existing web parts.
Bringing few questions to my notice.
1. Where do SharePoint persists the web part properties configured from settings?
2. Is there any way to read from object model?
