I had an old domain which was migrated to a new domain. However, for a few pages redirects are not working properly and still being indexed in results.

The migration was done a year ago.

Would it be wise to block the old domain through robots.txt or remove the URLs from link removal tool in GWT?

Solution :

Now, since you did the migration about a year ago and if you are happy with your current ranking then you may delete the old domain.

I wouldn't recommend blocking using robots.txt or URL removal tool.

If you can redirect to the respective pages then do that. If hard then let it go to 404 as Google might have signal about the move.
