One of my DotNet websites is having the mixture of upper case and lower case in most of the URLs (like.. /MyPage1.aspx, /MyPage2.aspx). Most of the pages are in search results same as the file name. But approx 10 pages are in results with only lower case URLs but their filename is as …MyPage3.aspx. For these pages, GSC is showing duplicate meta titles and descriptions in HTML Improvements.
Earlier canonical URLs was same as the running URL (URL working on both cases), but today canonical URLs is setup as their original filename(…/MyPage3.aspx). Means before today, 10 pages of my site which are on search results with lower-case URLs and having lower case canonical URLs, now has canonical URL as …/MyPage3.aspx. This will definitely resolve the issue of duplicate pages in GSC.
But I am worried about losing the rank of these 10 pages as their canonical is changed (/mypage3.aspx to /MyPage3.aspx).
Will it downgrade the ranking of these pages?
The website runs on the windows server and none of the URLs are on the search results with both cases till date.
Hope you understand the issue and suggest me the best possible way to overcome this issue.

I have created a directory and place the html landing page in it for adwords purpose. I just wanted to ask should I block the directory in robots.txt or it is not necessary. May be I can place more landing pages in the directory in future.
