Sitecore .Net Developer
I have single handedly upgraded a Sitecore instance for a pension regulator from 8.0 to 10.1 After starting the upgrade I found out that we can’t upgrade directly from 8.0 to 10.1 so I had to do a mini upgrade first from 8.0 to 8.1 and then from 8.1 to 10.1. The challenges and tasks I undertook are below:• Mini upgrade from 8.0 to 8.1 in multi environments• Installation of Sitecore 10 version• Solr Installation and configuration• Code integration and upgrade• Rewrite custom indexes and Pipelines• Rewrite search extensions and Caching• Upgrade the version of .Net framework of the solution and all other related projects• Installing/Configuring Identity server• Re-installation of Sitecore modules• Document each upgrade
