Internal job transfer
Not quitting and not starting at a new employer — moving to a different role or team inside the same company: negotiating terms, handing off current work, and the first weeks in the new spot.

[ ] Clarify the new role's terms before agreeing
    Salary, level, direct manager, probation expectations — get it in writing; an internal move shouldn't be settled by a hallway conversation.
[ ] Agree on the transition timeline with both sides
    The current and future manager can have different pictures of your start date — nail it down explicitly, in a message to all three of you.
[ ] Tell your current manager in person and early
    Before the news reaches them secondhand — even an internal move lands better when they hear it from you first.
[ ] Write a handoff document for current work
    Project status, contacts, where things live, what's urgent — the same principle as leaving a job, just the recipient might be a teammate down the hall.
[ ] Find out who's taking over your current duties
    If there's no successor yet, find out the interim plan so nothing falls through the cracks with no clear owner.
[ ] Check which access needs closing and which needs opening
    Old systems and channels, new team tools — usually goes through IT or HR, confirm the process ahead of time.
[ ] Keep the old team relationships warm
    You'll likely keep crossing paths inside the company — parting on good terms pays off faster than it seems.
[ ] Learn the new team's norms ahead of time
    Meeting format, tools, unwritten rules — ask the new manager before day one rather than figuring it out on the fly.
[ ] Ask to be introduced to key people on the new team
    A formal intro in the first week saves weeks of awkward 'and you are?' in chat threads.
[ ] Discuss a first-months plan with the new manager
    What's expected by the end of the first month and the third — ask directly rather than guessing.
[ ] Update your title in internal systems
    Email signature, internal directory, system access under the new role — a small thing that's easy to forget in week one.
[ ] Check how the move affects the current review cycle
    Who writes your performance review for the period — the old or new manager — and whether the transition gets accounted for separately.
[ ] Announce the move to wider colleagues appropriately
    A short note thanking the old team, with a way to stay in touch — keeps it professional and avoids rumors filling the gap.
[ ] Note for yourself why you decided to move
    Useful to revisit a few months in and check whether the expectations actually held up.
