wso2 - API manager, upgrade from 1.4.0 to 1.60 -

-

we're running wso2 api manager 1.4 , upgrade latest version 1.6. can go directly 1.6 or have upgrade 1.5 first? i'm concerned regarding db migration, these scripts seem relevant single version increments. https://svn.wso2.org/repos/wso2/carbon/platform/branches/turing/products/apimgt/1.6.0/modules/distribution/resources/

thanks.

as said, databases migrations, can execute migration-1.4.0_to_1.5.0 , migration-1.5.0_to_1.6.0 sqls sequentially.

it's important note api manager 1.4.0 based carbon 4.1.x , api manager 1.6.0 based on carbon 4.2.0. see release matrix wso2 products.

this means underlying clustering, registry , user-mgt have major changes. api manager related configurations has changed.

therefore advice follows.

  1. backup existing database , api manager 1.4.0 deployment.
  2. migrate databases in incremental manner.
  3. re-do configurations in api manager 1.6.0 instances. i.e. direct migration 1.4.0 1.6.0. may compare api manager 1.4.0 repository/conf files fresh wso2am-1.4.0 pack.

i hope helps!
