PR application information vs EE application information

[traveler1990]

When I submitted my EE application I used the company's new name for my work experience although, I was actually still employed there during the name change. In the referral letter for my PR application, my employer noted I was employed at the old name now new name. If I use the old name for my PR application noting the new name was on my EE application which was approved will this cause any issues?

Also, can information be updated in the PR application, still basically the same thing but fine-tuned, overall years of experience won't change or NOC code, based on the referral letter I am able to confirm some aspect of such as exact dates and exact hours which were maybe off by a day or off by an hour.
