Hi db_apha,
Generally, you don't need to upgrade transformers. That is of course, unless you read the "Show Changes" and see that the version notes suggests performance gains.
In my experience, any 'Spatial%' transformer that does overlay, filter, clipper or spatial analysis performs better in newer versions. The statisticsCalculator
To open the Version Information window, click the Version Information tab (bottom right), or select Version Information from the View menu.
Some of the benefits of upgrading transformers are:
- Performance and functionality improvements
- Bug fixes and enhancements
- New features and options
Other tips
- If there are multiple transformers, start upgrading the first transformer in the canvas and the changes flow through to the other same transformers.
- If you receive any upgrade warnings, this might mean the newer version has additional ports you need to map!
- Any attributes with spaces in them, may introduce incomplete transformers
- Many upgrades ask if you want to merge attributes as a default
- Some deprecated transformers have a new complimentary transformer replaced... e.g. S3Connector
