When to leave a tool, and how to do it without losing the year
Moving is expensive and sometimes right. The mistake is moving everything — the second system usually fails for the same reason the first did.
There are good reasons to leave: the price changed, the thing you relied on was removed, the company was bought and the product drifted, or you simply outgrew it. There are also bad reasons, and the commonest is that the current one is full of your mess and a new one is empty.
Telling them apart before you spend a weekend is the whole skill.
The question that separates them
Write down what specifically is wrong, in the form of an action you cannot take. "Cannot see this week and my money at once." "Cannot get my data out." "Cannot use it offline on the train."
If the list is concrete, moving may fix it. If the list is a feeling — cluttered, uninspiring, not quite right — then you are about to recreate the same clutter somewhere prettier, and you will know in six weeks.
Take less than you think
The instinct is to migrate everything, which imports the old mess and hides the benefit of the move. Take what is live: open commitments, things with a future date, documents that still matter.
Archive the rest where it is, or export it to one file you keep but do not import. In practice almost nobody goes back to it — but knowing it exists is what lets you leave it behind.
Leave the old one running for a month
Do not delete anything on the first day. Run the new one as the only place you add things, and keep the old one readable. A month later you will know exactly what you still reach for, and that list is short and specific.
Then close it properly: export, delete the account, and write down what you learned about why the last one did not fit. That note is the only thing that stops the next move from being the same move.
Before you go anywhere
Check that whatever you choose next will let you leave. A tool with no export is not a tool, it is a tenancy — and the day you want out is the worst day to discover the terms.
