Dear Experts,

I have some problem with my URL's.. Last week we migrated our website into new version from .asp to .aspx ..

Issue No 1:

After that, we got the problem in our URL that my website opens in both domain such as and . Everyone said that these two URL's are different . So, it will consider as a duplicate URL's in search Engines eye.

Issue No 2:

As same as, after migrated our website we found out the one more problem such as and . Everyone said that these URL's are also different URL's.

So, I am little afraid that I will get penalize by search engines for these errors.. Can anyone please let me know how to fix these two errors?
