The mechanics below apply whichever direction you are moving, including away from us. One practical consequence worth spelling out: because both directions work, you can run two tools in parallel during a genuine evaluation -- same proxies, split accounts -- and let a fortnight of real use decide, instead of committing on a feature table. That symmetry is deliberate: an export that only works inward is a lock dressed as a feature, and the test of any vendor on this page -- us included -- is how easily they let you leave.
Worth saying plainly first: if what you have works, switching for a feature you do not currently need is a bad trade. The good reasons to move are cost at your actual scale, a limit you keep hitting, or sessions that will not hold. Curiosity is not one.
Before any of the mechanics below: there is no rush, and no reason to move everything at once. A migration done over three weeks costs nothing extra and fails safely; one done in an evening is how people lose sessions they cannot get back.
The fear that stops most people moving between tools in this category is not price or features -- it is the several hundred live sessions they would have to re-establish, each one a sign-in, a verification code and a chance to trip something. That fear is reasonable and the answer is mechanical, so here it is in full.
A session is not held by the tool. It lives in cookies and local storage, which is why every product here can export them and every product here can import them. Export from what you are using now, import into a Dual Login profile, and the account arrives signed in. Three formats are read directly -- a JSON export, a Netscape cookies.txt, and a raw header string -- because those are the three people actually have, and converting between them by hand is where migrations stall.
What deliberately does not transfer is the fingerprint. That sounds like a limitation and is closer to the opposite: importing another tool’s identity would reproduce whatever a platform has already associated with it, including whatever made you want to move. A fresh, internally consistent identity paired with the same proxy is the better starting point, and the proxy is the part that must not change -- an account that has browsed from one address for months should keep browsing from it, because the address is the continuity a platform actually notices.
Move in waves rather than at once. Bring across a handful of low-value profiles, run them for a week alongside what you already have, and only then migrate the accounts you would miss. The mechanical part is quick -- profiles import from a CSV carrying name, group, proxy, start URL, country, notes and cookies per row, and proxies go into a shared pool once rather than being pasted per profile. The week of overlap is not wasted time; it is the only evidence that the sessions hold, and it costs nothing but patience.
One thing worth doing before you start: export your current sessions and keep the file somewhere safe, whatever you decide. That backup makes the whole exercise reversible, and a migration you can undo is one you can afford to attempt.
