Facebook is notifying page administrators that the company will begin phasing out the old insights tool on December 15.

On that day, the social network will stop collecting data for the old page insights. They will completely disappear from the site on February 15.

Facebook is advising page administrators who wish to save all data from December 15 and prior to that.

Currently, two different page insights icons appear on administrators’ dashboards. The one in the left-hand column leads to the new insights, while the one in the right-hand column (see first screenshot, above) goes to the old, where Facebook’s advisory about the transition appears at the top of the page.

Thanks to Kevin Evanetski, founder of Social Yeah, for pointing this out to us.
