Changing Job Title and profile after I-140 approval

[123whoknows]

My current Priority date is Oct 2014. I applied for GC through my employer in EB2 working as a Systems Architect. However I have an offer for a new profile as in Information Security Principal in the same company in a nearby location office.

I wanted to know how will this impact my green card processing in progress.

1. Would I need to apply for a new PERM?

2. If #1 is Yes, do I get the same PD or would I get a new PD as of the new PERM (which might be after 2018)?

Any other inputs or suggestion, are always welcome that I might have not considered.

1. Yes

2. Old PD is retained.
