Notes:
Moving to ArcGIS Pro 3.3 SDK (or 3.0 SDK) from 2.x is not an upgrade. To install,

1. Consult Migrating from 2.x if you want to install ArcGIS Pro 3.3 SDK and you are on 2.x, not 3.x.
2. If you are migrating a 2.x add-in to 3.3 you can install the migration tool to help automate the conversion process. Moving from 2.x to 3.x is a breaking change. Refer to the migration guide ProConcepts: 3.0 Migration Guide and ProGuide:.NET 8 Upgrade for more details.

Read the ProGuide: Installation and Upgrade for detailed installation instructions.
