Why redirect? A very good thing about Episerver Commerce is that even you enabled the partial routing system, the old SEO Uri:s will continue to work (of course, as long as you keep the Uri:s unchanged). So they can coexist in same website – but that might not what you want – you...
Something I have to say Interesting or not
While I’m proud of how great Commerce were in 2014, there are still areas where we need to improve. One of those is performance.
We paid attentions to important parts of the system, where customers demand the most. And the results were, quite impressive. From 8.11 to 8.15, many profiling and improvements had been done, and the results are quite expensive: loading cart performance increased with a fold of 4, loading Entry with CatalogEntryResponseGroup.Full performance increased with a fold of 3, etc.
