If you’re switching from Greenlight Guru — or just quietly wondering whether you could — the single thing holding most teams back isn’t the decision. It’s the dread of migration: years of controlled documents locked in one system, and the fear that moving them means months of manual re-entry. That fear keeps a lot of companies paying for software that no longer fits, simply because leaving feels harder than staying.

Here’s the part worth knowing before you assume you’re stuck: moving your documents from Greenlight Guru to TLM is automated. This is a straight, fair look at why teams switch, what the migration actually involves, how the document transfer works — and, for regulated teams, why re-validating on TLM is easier here too.

Why companies consider switching from Greenlight Guru

First, credit where it’s due: Greenlight Guru is a capable, medical-device-focused eQMS, and for plenty of companies it’s the right tool. (For a side-by-side, see our Greenlight Guru comparison.) Switching isn’t about it being “bad” — it’s about fit changing. The teams that reach out to us are usually in one of these situations:

• It’s more than they need. A smaller or earlier-stage device company finds they’re paying for — and navigating — a platform built for larger, more complex operations.
• They want more flexibility. Their process doesn’t fit the template, and they’d rather the software bend to how they work than the other way around.
• Cost has outgrown value. As they’ve grown or their needs have shifted, the price stopped matching what they actually use.
• They want the same compliance with a lighter footprint — full ISO 13485 and 21 CFR Part 11 document control, without the weight.

If none of that sounds like you, staying put may well be the right call. If some of it does, the next question is the one that actually matters.

The real blocker: “we can’t move all our documents”

This is the objection that keeps teams frozen — and it’s a reasonable one. Your controlled documents are your quality system’s memory: procedures, work instructions, revisions, the whole history. The thought of exporting all of it and rebuilding it by hand in a new system is enough to make anyone stop reading a comparison page and close the tab.

So let’s take that fear off the table directly.

How document migration from Greenlight Guru to TLM works

TLM has a bulk document import that connects to Greenlight Guru’s API. In plain terms:

• Using your own Greenlight Guru account credentials — your data, your authorization — the import reads your documents from Greenlight Guru through its API.
• It brings your controlled documents into TLM in bulk, rather than one-at-a-time by hand.
• We run it with you, verify the results against your source system, and get your documents into TLM’s controlled structure — versioned, and ready to keep managing.

It’s your data, moved with your permission, by an automated process — not a summer of copy-paste. And it’s not theoretical: we built and proved this migration on a real medical-device company’s live Greenlight Guru account before we ever offered it to anyone else.

What the switch actually looks like

A migration is a project, not a light switch — but a well-run one is measured in a handful of guided steps, not months:

1. Assessment. We look at what you have in Greenlight Guru and what you want in TLM, and map how your documents and structure carry over.
2. Connect. The import is configured against your Greenlight Guru account.
3. Import. Your documents are pulled in bulk into TLM.
4. Verify. We check the imported documents against your source system so nothing is missed.
5. Go live. Your team starts working in TLM — with onboarding support so adoption is smooth, not a cliff.

Records and history beyond your documents (things like training, CAPA, and audit data) are handled as part of that assessment — we’ll tell you honestly what comes over automatically and what we bring across with you, rather than promising magic.

The second fear: re-validating a new system

For a medical device company, data migration isn’t the only thing that makes switching feel heavy — validation is. Moving to a new quality system means validating it, and re-validating on future updates. For a lean team, that prospect alone can freeze a decision. So it’s worth knowing this is the other place TLM is built differently, along four lines — two of which a multi-tenant platform structurally can’t offer:

• What — risk-based, CSA-aligned. Validation should test what actually matters, not generate paperwork for its own sake. That’s the FDA’s own current position: the 2025 final Computer Software Assurance (CSA) guidance endorses risk-based assurance — outcomes over documentation. (CSA applies to cloud/SaaS platforms too, so this is a smarter way through validation, not around it.)
• How — guided validation routines. Instead of granular test scripts, TLM expresses validation as whole-workflow routines — “create a document, have two reviewers approve it, release it with training required, and verify the result” — grounded in your own system’s settings and expected outcomes.
• When — you control the timing and scope. Because every TLM client runs on their own single-tenant instance, you decide when an update is applied and validated. You’re never force-pushed onto a vendor’s release schedule mid-quarter. A multi-tenant platform updates everyone at once — you validate on their calendar, not yours.
• Authored — the AI scopes the exact gap. This is the part that’s genuinely hard to copy. TLM’s AI (we call it Sensei Claude — guided, auto-scoped validation routines) compares your current version to the target and proposes a validation set covering exactly what changed for you — not one generic package sent to every customer. Your Management Rep reviews, adjusts, and approves it: the AI proposes, your quality unit disposes, and the record proves it.

The honest boundary: this accelerates and scopes your validation — it doesn’t do it for you or guarantee compliance. Your quality unit still owns the determination and signs the records. But it turns the scariest part of switching — “we’ll be validating forever” — into something a small team can actually manage.

A multi-tenant competitor can match the idea of risk-based validation. It can’t match the substance: it doesn’t run on your own instance (so it can’t give you control over timing), and it can’t scope validation to your specific changes (everyone gets the same update and the same package). That’s not a gap TLM out-built — it’s structural.

Is switching right for you?

Honestly: not for everyone. If Greenlight Guru fits your size, budget, and process, there’s no prize for switching. But if you’re a small or mid-sized device company that wants the same ISO 13485 and Part 11-grade document control with more flexibility, a lighter footprint, and a price that matches your reality — and the only thing stopping you was the migration — that blocker is smaller than you think.

Where TLM fits

TLM is built for the small and mid-sized quality team that needs real compliance without enterprise weight: controlled review and release, 21 CFR Part 11 electronic signatures, obsolete-document control, training tied to each release, and a complete audit trail — configured to your process, backed by onboarding that gets your team actually using it. Add automated migration on the way in, and switching stops being the scary part.

Frequently asked questions

Can you migrate documents from Greenlight Guru to another system?
Yes. TLM offers a bulk document import that connects to Greenlight Guru’s API and, using your own account credentials, brings your controlled documents into TLM automatically — instead of manual re-entry.

How do you export your data from Greenlight Guru?
Your data is yours to export. For a move to TLM, the automated import reads your documents from Greenlight Guru through its API using your credentials, so you don’t have to manually download and re-upload everything by hand.

How long does it take to switch from Greenlight Guru to TLM?
It depends on the size of your document set and how much you’re bringing over, but because the document import is automated and guided, most migrations are measured in a handful of steps over weeks — not the months teams fear.

Will I lose my document history if I switch?
No — the goal of a controlled migration is to preserve your documents and their versions in TLM. Part of the assessment is confirming exactly what carries over so nothing important is left behind.

Is switching from Greenlight Guru worth it?
Only if the fit has changed — if you want the same ISO 13485 and Part 11 compliance with more flexibility, a lighter footprint, or a better price. If Greenlight Guru still fits, stay. If it doesn’t, automated migration removes the main reason to put the decision off.
