From Yeastar to Thirdlane: one platform, no ceiling.
Yeastar P-Series is a solid fit for one business. Serving many customers is a different job — a separate system per customer to buy, manage, and maintain, and a size limit that forces a bigger box or a second system when a customer grows.
Thirdlane brings all of those customers onto one platform you control — with your brand on the apps, better economics per customer, and room for customers of any size. Here’s what moving looks like, in plain terms.
Bottom line
Migrating from Yeastar to Thirdlane consolidates per-customer P-Series appliances onto one multi-tenant platform, in three phases — map, run side by side, then cut each customer over on a schedule you control. Extensions, numbers, auto-attendants, queues, and voicemail come across, customers of any size fit on the same platform, and end users keep dialing as they always have.
- One platform instead of a separate Yeastar appliance per customer — no size ceiling.
- Per-customer cutover on your schedule, with no end-user downtime.
- Numbers, IVRs, ring groups, queues, greetings, and voicemail migrate across.
- White-label apps under your brand; you keep ownership of device provisioning.
Why MSPs make the move
Lower cost to run
Instead of a separate system per customer to manage and maintain, you run one platform. Less hardware, fewer moving parts, and far less routine upkeep as you grow.
Better margins
More capability included and per-tenant economics, so growth doesn’t mean stacking up more boxes and more licenses. Your costs stop tracking your customer count one-for-one.
No size ceiling
Big customers and multi-location businesses fit on the same platform as everyone else — no swapping to a bigger appliance or linking systems together when a customer outgrows what they started on.
Your customers stay yours
Apps carry your brand, not the vendor’s, and you keep control of your customers’ phones and provisioning — always yours to manage or move.
More in the box
Contact center, CRM, messaging, and AI call intelligence are built into the platform, not separate add-ons to license and stitch together.
No disruption to end users
Phones keep working through the switch and people keep dialing the way they always have. The change happens behind the scenes.
Everything comes across
A move is only worth doing if nothing important gets left behind. We bring over the things your customers rely on every day:
- Your people and their phone numbers
- Auto-attendants and menus that greet and route callers
- Ring groups and call queues
- Greetings, announcements, and hold music
- Voicemail
One difference worth calling out: with Thirdlane you own your customers’ phone provisioning, so their devices are always yours to manage or move. We explain why that matters in You Bought the Phones. Do You Own Them?
How the move works
Step 1
We map your setup
We take stock of your Yeastar systems and customers and produce a clear plan for each one — what moves as-is and what’s worth tidying up on the way.
Step 2
We run both side by side
Thirdlane is stood up alongside your existing Yeastar systems and pre-loaded, so nothing is a leap of faith. Your current setup keeps running the whole time.
Step 3
We switch each customer over
Cutover happens one customer at a time, on a schedule you control, with no downtime — and we keep the old system available until everyone is settled.

Why move from Yeastar P-Series to Thirdlane?
