Changing PI tag names without losing data

Hello everyone,

 

I need to rename some PI tags without losing historical data. Is it possible to change the tag names directly (using PI SMT or PI Builder, Edit only). Another option is to create new tags, backfill data from the existing tags to the new ones, and then remove the old tags. How will the new tag names affect my analysis and event frame (and attributes), if I do and don't rerun and backfill the analysis?

 

Anyone has done that before, can you please share your experience? Thank you!!!
