This affects versions of Umbraco 7.3.0 -> 7.4.3 when running Courier deployments for Member Type changes. Specifically, the data loss issue occurs when:
The members themselves will not disappear but all custom properties are wiped.
This issue is due to an Umbraco Core bug between 7.3.0 -> 7.4.3. Whenever a Member Type is saved in the core, new GUID/Unique IDs are generated for all Member Type Property Types and Property Groups. Since Courier relies on GUIDs being consistent between environments, Courier will assume that all of the Property Types and Property Groups have been removed and new ones have been added. The data loss occurs because when a Property Type is deleted, so is all affiliated property data.
The Umbraco Core fix is detailed here: http://issues.umbraco.org/issue/U4-8569 This fix will be rolled out with a the new 7.4.4 version in the coming couple of weeks.
A new version of Courier (2.52.7) will be released asap to mitigate this issue. This Courier release will:
This will only affect Member Types, this will not affect Content/Media Types and renaming of Property Types/Groups for Content/Media types will continue to work as expected.
Have reviewed the code changes and have tested this by:
