are there api changes document for SDK 6.x to 7/8/9 ?

[sprhawk]

I'm migrating firmware from SDK 6.x to 9.0.0

I found pretty many changes in SDK APIs.

Do I have need or do you recommend to upgrade to new SDK ( for bugs / problems resolved , more efficient (not in space at least ), or for future upgrade ( will you not change future APIs again ?))

Are there any document besides release notes ( I think it has no use for migration ) to help me the migration process ?

Hi

There is no migration document available to help with the migration between major SDK versions. The SDK release notes is the primary document to look at to realize if what has changed and if it actually is relevant to your scenario.

The nRF51 compatibility matrix table 4 shows what SDKs are compatible with which hardware revision. If you have nRF51 revision 2 hardware, SDK 7+ is not compatible as those SDK versions are not tested or implemented for the second revision.

Perhaps the easiest way to migrate between SDK verisons is to take you custom code from SDK 6 and copy that into a template project in SDK 9.
