The present invention provides a process for upgrading a Fischer-Tropsch product by hydrocracking in the presence of a hydrocracking catalyst in a reactor, wherein the process is initiated by a series of steps (i) to (iv). The hydrocracking catalyst is (i) contacted with a hydrogen-containing stream having a feed temperature of from 360&#xb0; C. to 420&#xb0; C.; (ii) the feed temperature of the hydrogen-containing stream is reduced to a temperature of from 220&#xb0; C. to 280&#xb0; C.; (iii) the catalyst is contacted with a Fischer-Tropsch product stream having a feed temperature of from 220&#xb0; C. to 280&#xb0; C., which is co-fed with the hydrogen-containing stream; and (iv) the catalyst is co-fed with a Fischer-Tropsch product stream and hydrogen-containing stream having feed temperatures of from 380&#xb0; C. and 400&#xb0; C. for at least four days and wherein the hydrocracking catalyst is not activated by sulfiding.
