Updating the module to DFS 10.4.0
Install the new DAM for Sitecore-10.4.0-U.zip package and overwrite all when asked.
After updating:
If you are upgrading from DFS 8.x, follow this step otherwise continue to the next step. Since we removed the DFS membership provider. You have to assign the rolesitecore\Digizuite DAM for Sitecore Usersto the user extranet\Anonymous. If you don't do this, you won't be able to see any DFS assets on the public website as the anonymous user.
Add the silo item through the Installation Wizard again which you packed in step 2a.
Note It is important to delete the data of the index dfs_assets_master_index, before doing a full synchronization of the silo. If you don't do this, the full synchronization will fail.
If you're updating from below 10.0.0, then continue to the following page: DFS 10.4.0 - Keeping the Silo Updated. If not, then you can skip this step.
Now you should be fully done with the update.
