We're working on the Sitecore upgrade from Sitecore 7.2 to Sitecore 9 update2. Using the express migration tool, we moved all the content from sitecore7.2 to sitecore 9 initial version and updated the references and breaking changes and it almost works fine.
To move from Sitecore 9 initial version to Sitecore 9 update 2, There are some upgrade scripts which are available.
Note: Current project is not using any DMS functionalities and sitecore customization is very less.
I have a couple of questions.
Shall i take the packages from sitecore 9 initial version and install the package to sitecore 9 update2 directly since i don't have much sitecore customizations and No XDb migrations?
When do we follow upgrade option? ( i mean upgrading from sitecore 9 Initial version to Sitecore 9 update2 using Upgrade scripts and Upgrade packages)?
