I have downgraded one site from magento enterprise to community edition based on the below blogs/forums, after that we have made few changes to the site work perfectly in the community edition. And the site working fine now and it's live with community version.

And we have applied for the Certification of Compliance to the magento team to close the enterprise agreement, however we got the reply from the magento team there are still few elements related to enterprise code still in the site and needs to be clean up to close the agreement.
We have cross checked the site very closely but we are unable to find a code/option related to enterprise code, even we have requested to the enterprise team to provide the documents/reports which show the enterprise code still in the site but it seems like they will receive the status as true/false, that's it. They don't have any other details.
And let us know, is there any proper tool or suggestions to cross check and find the enterprise code with the site.
Thanks in advance for your support.
