Mohammed ..

Its better to use the updated datasets (for example, ee.ImageCollection("LANDSAT/LC08/C02/T1_L2")). But you can use the deprecated datasets, totally depends on you. But the updated datasets are of better quality.

Check this link

(https://forum.sentinel-hub.com/t/deprecation-of-landsat-8-usgs-collection/3495).

Akib Javed

Use the following link instead

ee.ImageCollection("LANDSAT/LC08/C02/T1_L2") for Landsat 8

ee.ImageCollection("LANDSAT/LE07/C02/T1_L2") for Landsat 7
