After running the Update Installation Wizard for a Sitecore solution from Sitecore 8.1 Update-1 to Sitecore 9.0 Update-2 we discovered that the order of most of the renderings on page items had changed. Beforehand we already tested an upgrade with Sitecore 9.0 Update-1 for this solution and it worked perfectly fine. This implied that something must have changed between Sitecore 9 Update-1 and Update-2. Weiterlesen
First of all some words about Sitecore and Upgrades
When I was a beginner in Sitecore developement, the Sitecore world stands almost still for several months to years with the release of Sitecore 6.5.
So what I want to say with that is the product was more or less very stable with few small issues and no big need to update the solution for business or technical reasons.
What we did was creating wonderfull solutions without thinking to much about „how we will update/upgrade this in the future“. In my opinion Sitecore haven’t done the same in that dimension they have to do it now.
Often a Sitecore infrastructure consists of a single server instance with two – maybe three – environments (development and production) which was easy to maintain and handle.
Years go along management environements separate from delivery machines more and more, single server instances disappear in many cases to high scalable solutions with multiple servers for webapplications, sql servers, mongodb instances. Publishing instances and third party products not included.
On the other hand, we all get a little bit older: the employees searched for new challenges in other companies and you remember them only from some years ago.
