kentico upgrade issue from version 10 to 11

Shohei Kodama asked on January 31, 2020 04:49

I'm verifying a site version upgrade from Kentico 10 to 11 locally. Upgrading to Kentico11 using the Kentico Upgrade Utility was no problem.

However, no matter which page you access (such as the TOP page), you will see page 503 and you will not be able to access the kentico administration screen with / admin.

Would you please tell me how to isolate this issue and any advice?

In the IIS logs you sent, there is also a 401 - unauthorized error. How is your local instance configured? Are the disk permissions set correctly for the Network service user account (used by the application pool)?
Anyway, I would try restoring the v10 backups, make sure you are able to load the site, access admin interface and upgrade again.

What are the error details - any more detailed error logged in the CMS_EventLog table or in the Windows event viewer? What were the upgrade steps? It looks like it did not went that well...Have you tried restoring the backups and upgrading again?

A 503 error is typically a stopped Application Pool or website. Check in IIS to make sure the app pool is running, on version 4.0 and the website is running. If it was running and keeps stopping, then there is a code issue causing IIS to fail. In this case, build your code on your local machine to see if it builds properly. If not, fix the errors and try again.

Thank you for your message.

I answered the following questions.

  • What are the error details - any more detailed error logged in the CMS_EventLog table or in the Windows event viewer?
  • I checked the CMS Event_log table, but no new event logs were created.
  • The Windows event log created when debugging in the local environment is as follows.

Hi Brenden,

Thank you for your message.

I answered the following questions.

  • A 503 error is typically a stopped Application Pool or website. Check in IIS to make sure the app pool is running, on version 4.0 and the website is running.
  • Yes, the IIS application pool appears to be running on 4.0.(Please check the attached file "gcms-dev-roland" site)

IIS Application pool

  • In this case, build your code on your local machine to see if it builds properly.
  • On the local machine, the build was successful and when I debug, I get a 503 error.

Please let me know if you have any other things to check.

Thank you everyone.

After merging the .new file created by the Upgrade tool and deleting the app_offline.htm file, the site started up without any problems. I will be carefully read the documentation.

I'll let you know if I have any questions.
