Priority date port from old i140 with completely different soc code


I have a question regarding priority date port . I worked for company A which applied eb2 i140 for me in soc code for sales engineer. I moved to another company and new h1b as system analyst. They will apply new perm and i140 in a year or 2 under system analyst . Question is can I retain same priority date from i140 which was for sales engineer? I don’t care if it’s eb2 or eb3 on new i140 . Just want to keep the same priority date.

You may be able to port the priority date if the new job is in the same or similar field. In most cases, your employer or attorney will be able to do it if approximately 50% of the job duties are the same.
