Narrative:
On takeoff we noticed an unknown odor in the flight deck. The #1 engine had previously been changed. Flight attendant a called and they also smelled the odor in the cabin. As we climbed out the odor seemed to be dissipate. We looked at the smoke/fire/fumes checklist and determined it was not applicable to our situation. The flight attendants said the odor seemed to have somewhat cleared up so we continued on to ZZZ. They said the odor came back on the descent into ZZZ so we wrote it up when we landed. We also did a logbook entry and maintenance had me fill out the paperwork for odor in the cabin.
