Restore Legacy CDRs - would you do it or not?

What has your experience been with Restore Legacy CDRs? I just tested it. Shows up fine in CDR Reports. However, it is not that consistent within UCP. It shows up fine in Call History Widget for some extensions but the records are missing for some extensions even though they are in CDR reports within Freepbx Admin.

Also, I feel it just makes the system clunky within UCP with the call history widget taking a long time to load all that CDRs in the Call History Widget. I feel it is better to archive it somewhere else.

What are your thoughts?

Thanks.
