Search Service Application problems after upgrading from Foundation to Enterprise edition of SharePoint 2013

Question

Hi all. I have been searching for days for a solution to a problem I am having with SP2013 Enterprise edition.
We recently upgraded from SP2013 Foundation to SP2013 Enterprise. After the upgrade, the search services are no longer working and we are receiving many application log entries indicating the following:
Application Server Administration job failed for service instance Microsoft.Office.Server.Search.Administration.SearchServiceInstance (ea2019ef-bb9e-4efe-85ee-5d2307406f31).
Reason: Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED))
Technical Support Details:

   at Microsoft.Office.Server.Search.Administration.SearchServiceInstance.Synchronize()
   at Microsoft.Office.Server.Administration.ApplicationServerJob.ProvisionLocalSharedServiceInstances(Boolean isAdministrationServiceJob)
as well as:
Application Server Administration job failed for service instance Microsoft.Office.Server.Search.Administration.SearchServiceInstance (ea2019ef-bb9e-4efe-85ee-5d2307406f31).
Reason: The object you are trying to create already exists. Try again using a different name.

   at Microsoft.Office.Server.Search.Administration.SearchServiceInstance.Synchronize()
   at Microsoft.Office.Server.Administration.ApplicationServerJob.ProvisionLocalSharedServiceInstances(Boolean isAdministrationServiceJob)
I have tried to remove the search service application and recreate it, and even though the SharePoint Central Administration states that it was created successfully, I am still getting the same errors in the log. If I go to the Search Service Application
Search Administration page, the "System Status" shows the following message:
The search service is not able to connect to the machine that hosts the administration component. Verify that the administration component '0359af35-0982-4ede-8838-b1d390e915bf' in search application 'Search Service Application' is in a good state and
try again
Additionally, under the "Search Application Topology" section, it states "Unable to retrieve topology component health states. This may be because the admin component is not up and running" which I assume is normal if the admin is not
running.
Does anyone know how I can resolve this problem? 
Thanks!

Hi Joaquin,
According to your description, the error occurred when you re-created the Search Service Application.
Based on the error message, I recommend to verify the things below:
   1. Check if the association between the Search Service Application proxy and the web application is configured.
Please go to Central Administration > Application Management > Configured service application associations > Click Default to see if the Search Service application is checked.
   2. Change the app pool for the Search Service Application to SharePoint Web Services Default in the properties of the Search Service Application.
Please go to Central Administration > Application Management > Manage service applications > Highlight the Search Service Application > Click Properties in the ribbon > Change
the two app pool to SharePoint Web Services Default: App Pool For Search Admin Web Service and Application Pool for Search Query and Site Settings Web Service.
    3. Run PS command to check if the search admin timer job is enabled: Get-SPTimerJob
job-application-server-admin-service | fl. If it is not enabled, use PS command to enabled it and then reset Internet Information Services: Enable-SPTimerJob job-application-server-admin-service.
Best regards.
Thanks
