Question 0.51 upgrade to 1.0.0-prev15

Is there a migration guide from Entities 0.51 to 1.0.0?

For example, I'm trying to understand what I need to do with converting my worldspace position and rotation to the new Transforms components (all my calculations are currently in WS). Do I need to add a WorldTransform component (rather than individual Translation and Rotation components?

Code (CSharp):

1. Entity entity = entityManager.Instantiate(projectilePrefabEntity);
2. ..
3.  
4. // Set their position, rotation and projectile properties
5. // Shift the position forward by the weapon velocity, so that projectiles don't ever end up behind the ship
6. entityManager.SetComponentData(entity, new Translation() { Value = (float3)position + (_velocity * deltaTime) });
7. entityManager.SetComponentData(entity, new Rotation() { Value = quaternion.LookRotation(startFwdDirection, startUpDirection) });
8. ..

I'm assuming I need to do something like the following, but not sure.

Code (CSharp):

1. #if UNITY_2022_2_OR_NEWER
2. // Set position from world origin
3. LocalTransform localTrfm = entityManager.GetComponentData<LocalTransform>(entity);
4. localTrfm.Position = (float3)position + (_velocity * deltaTime);
5. localTrfm.Rotation = quaternion.LookRotation(startFwdDirection, startUpDirection);
6. entityManager.SetComponentData<LocalTransform>(entity, localTrfm);
7. #else
8. entityManager.SetComponentData(entity, new Translation() { Value = (float3)position + (_velocity * deltaTime) });
9. entityManager.SetComponentData(entity, new Rotation() { Value = quaternion.LookRotation(startFwdDirection, startUpDirection) });
10. #endif

Also, I have some ScheduleParallel IJobChunk jobs using a class derived from SystemBase. Should I now be using a struct derived from ISystem? Are there any conversion guidelines for this?
