Hi all, quick question from someone who never worked with visualforce pages before. We have a custom object (RFQ) where few fields need to be updated using code. These fields will be populated from the related list on Account (lookup) which is then used in RFQ record (lookup to Account).

Need to confirm the following: 

• Will it be the current page on RFQ record that will use the code to pull the data just for the fields we need, or will it be the whole page that needs to be replaced with a custom developed (VF) page? 
• Do you see any risks with using this VF approach keeping Lightning in mind as a future state?
