The Obama administration is dismantling a dormant national registry program for visitors from countries with active terrorist groups — a program that President-elect Donald J. Trump has suggested he is considering resurrecting.

The registry, created after the attacks of Sept. 11, 2001, has not been in use since 2011, so the move is largely symbolic and appeared to be aimed at distancing the departing administration from any effort by the new president to revive the program, known as the National Security Entry-Exit Registration System, or Nseers.

Asked on Wednesday, in the aftermath of the Berlin attack, whether he still intended to set up a registry for Muslims and impose a temporary ban on Muslim immigrants, Mr. Trump said in Florida, “You know my plans.” Hours later, a spokesman said Mr. Trump was not reaffirming his earlier calls for a ban on immigration from Muslim countries but was referring to his more recent clarification that he would bar people from countries with a history of Islamist extremism.

The move by the White House to formally end the registry is among the actions being taken in the final weeks of the administration that could prevent, or at least slow, what Democrats fear may be a swift rollback of President Obama’s efforts on immigration and climate change.
