README

Provides tasks for upgrading the assets folder from Silverstripe 3 installs for Silverstripe 6+, this is a port of code from Silverstripe 4 that was removed in Silverstripe 5

Maintainer Contact

• Ed Chipman (UndefinedOffset)

Requirements

• Silverstripe Assets ~3.0

Installation

Composer (recommended):

composer require webbuilders-group/silverstripe-file-upgrader

Class Mapping

Silverstripe > 4.x uses full qualified namespaces. To ensure proper class name resolution during migration, add at least the following:

SilverStripe\Dev\Command\DbBuild:
  classname_value_remapping:
    File: SilverStripe\Assets\File
    Folder: SilverStripe\Assets\Folder
    Image: SilverStripe\Assets\Image

Image Processing Considerations

If you encounter errors during thumbnail generation (e.g., ImagickException: Unable to set image colorspace), consider switching from ImageMagick to GD driver for the migration:

SilverStripe\Core\Injector\Injector:
  InterventionImageDriver:
    class: 'Intervention\Image\Drivers\Gd\Driver'
