I have Renovate running once every hour for my projects. After configuring similar schedules for both branch & PR creation (schedule) and automerge (automergeSchedule), I observed that even though automerges were enabled they were never in schedule according to debug logs.

Following the documentation and examples from schedule page and the claim that automergeSchedule supports the same syntax as schedule, I created the following config.

    "schedule": ["after 8pm and before 4am"],
    "automergeSchedule": ["after 8pm and before 4am"],

After having a closer look into Debug logs I discovered that during startup Renovate logs Config migration necessary. When observing the differences in the new config we see that the schedule field is migrated to a more logically correct format ["after 8pm", "before 4am"] while the automergeSchedule stays at the logically impossible ["after 8pm and before 4am"].

I was able to work around the issue by adding the migrated syntax for automergeSchedule already into the config. However, I reckon that ScheduleMigration should also apply for the automergeSchedule field values since the documentation claims that the syntax is handled identically.
