Umbraco-v7-Upgrader

Use this repo to upgrade an Umbraco v7 database to v9.

Notes

The process followed was as suggested by ProWorks in this blog post:

https://www.proworks.com/blog/archive/how-to-upgrade-umbraco-version-7-to-version-8

The upgrade process listed in this readme worked for an Umbraco database that started life as version v7.12.4. The site used nested content, various pickers etc but only core property editors, so several of the steps in the blog post were not relevant for this site.

Process

Open src/Umbraco-v7-Upgrader.sln in Visual Studio and build.

Step 1: Upgrade to v7.15.7

The v7.15.7 project in this solution is a 'vanilla' install of Umbraco with the following installed:

  • ProWorks' Our.Umbraco.Migrations package. This will perform some needed migrations when upgrading to v7 latest.
  • Steve Megson's Pre Migration Health Check package. This adds a health check which can fix some issues before the v8 step.
  • Dan Booth's God Mode package. This allows us to check what data types use nested content.

Steps to follow:

  • Expand the Umbraco-v7-15-7 project, and edit web.config:

    • Update <add key="umbracoConfigurationStatus" value="" />: set the value to be the current Umbraco version of your database
    • Update the umbracoDbDSN connection string to point to your database

  • View the Umbraco-v7-15-7 website in the browser and authorise the upgrade (don't worry that it reports the wrong current version in the dialog)

  • Backoffice > Developer Section > Health Check > 'Migration' group

    • Click 'Check group'
    • Fix any issues reported

  • Backoffice > Developer Section > God Mode > DataType Browser

    • Make a note of the data types that use the Umbraco.NestedContent property editor, and the document types that those data types references

Step 2: Upgrade to v8.17.2

The v8.17.2 project in this solution is a 'vanilla' install of Umbraco with the following installed:

Steps to follow:

  • Expand the Umbraco-v8-17-2 project, and edit web.config:

    • Update the umbracoDbDSN connection string to point to your database

  • View the website in the browser and authorise the upgrade

  • Backoffice > Settings > Document Types

    • Check that all the nested content document types are flagged in 'Permissions' as 'Is an Element Type' (if not, update them and Save)

Step 3: Upgrade to v9.2

The v9.2 project in this solution is a 'vanilla' install of Umbraco.

Steps to follow:

  • Expand the Umbraco-v9-2 project, and edit appsettings.json:

    • Update the umbracoDbDSN connection string to point to your database

  • View the website in the browser and authorise the upgrade

Acknowledgements

  • Massive #H5YR to ProWorks for the blog post and the migration tools that they released

  • Also to Steve Megson for the v7 Pre Migration health check package

  • And finally to Dan Booth for the God Mode package that is an essential tool for understanding what's used where in an Umbraco install
