I have Question, Anyone can help on this.

I have one website in **Magento 2.2.1**, Now We are planned and Upgrade Website in  **2 instances one from Composer and Another from Manually Way**(Downloaded form Magento Website).

**Now we are on the point where we found many differences while comparing Vendor Folder of Both Instance after Upgrade.** 

**My Findings Like** - 

 - 23 New Directories added in Manually Upgrade while Composer instance does not have.
 - Many Files have difference while compare
 - Manual Upgrade have Many modules from vendor have Upgraded versions while composer does not have.
