You did all that was not right for your website. Now you will need to wait because it is a long and tedious process. Check the 404 errors issue in the webmaster tool and try to fix that.
I cleaned all the issue, including from the BIT pages that gave the code 404.
As I wrote above, after the change of CMS in the search, there were about 3500 broken pages and only 200 live.
Is it not easier to remove everything from the index and re-index the site as it was already which had 2000 pages without broken links?
Google will consider them as new pages, and not old (you changed URLs) - will be non-unique content, since old pages, in its algorithms are still alive. 301 should have been updated! Positions can persist strongly, 2 days are not deadline, add redirect to new pages now.
1) About the content, I did not understand because I checked a bunch of services - my content is indexed, it is unique because my site is not present in the index. Is there any algorithm for this?
2) Already had a good amount of organic traffic per month, but did not observe the pages of the store.
