SAP Commerce Accelerator从2005升级到

In order to upgrade B2B Accelerator, you also need to upgrade Platform, commercewebservices, and B2C Accelerator, so you would start by opening the relevant pages for all these packages.

B2B Accelerator的依赖是platform，commercewebservices和B2C Accelerator，因此后三者也要分别进行升级。

对于Hybris extension的升级策略，SAP给出的guideline是：

• 升级所有的常规extension：Upgrade all regular extensions (for example solrfacetsearch, backoffice)
• 不要升级所有的template extension：Do not upgrade template extensions (for example the Accelerator extensions)
• Reuse custom extensions

Over the years various Accelerators (B2C, B2B, Telco, China, Financial, Travel, etc.) have been introduced to help provide a consistent foundation of code that would save many people days up-front, but it can result in more difficult upgrade projects. This is because as soon as you generate the Accelerator extensions and make a single change to the generated code, you’ve created custom code. Every additional change you make to the generated Accelerator extensions increases the level of customization.
