[CLOSED] Upgrading page from 8.2.1 to 8.5.1.
we are looking for someone who would upgrade our page from c5 8.2.1. up to 8.5.1. (latest version). I know how to upgrade by myself, but everytime I do, I keep running in the same issues. Some pages (not all) stop working and are throwing different errors (Entity type not found, Foreign key restraints, AttributeValues avID not found and so on). Also some CRON jobs are failing after upgrade also. We are looking for someone who can upgrade and fix all this issues.
Thank you for your help.
