“How long will this take?” and “What will this cost?” are the first two questions every organization asks before starting a SharePoint migration. The honest answer is that it depends, but not on anything mysterious. A handful of factors determine both, and once you understand them, you can make an informed call on the right approach for your organization.
What Drives Your Migration Timeline
Every migration timeline comes down to the same core variables:
- Content volume: how many sites, libraries, and items need to move.
- Customizations: InfoPath forms, SharePoint Designer workflows, custom web parts, and farm solutions all add time.
- Site complexity: subsites, nested permissions, and inconsistent metadata slow things down.
- Internal availability: how much time your team can realistically give to decisions, testing, and validation.
- Testing and training: user acceptance testing and change management are part of the timeline, not an afterthought.
Organizations with straightforward environments and little customization can often move in a matter of weeks. Add InfoPath forms, workflows, or complex permissions, and that timeline stretches to a few months.
What Drives Migration Cost
Cost tracks closely with timeline, plus a few factors of its own:
- Whether content moves as-is or gets modernized and restructured along the way.
- How many legacy customizations need to be rebuilt versus retired.
- How much of the work your internal IT team can take on versus what a migration partner handles.
- The scope of post-migration training and support.
The biggest cost driver, by far, is customization. A clean lift and shift of standard document libraries can cost much less than a migration that requires rebuilding InfoPath forms and workflows from scratch.
Key Decisions You’ll Need to Make
Lift and shift, or modernize now?
You can move your current structure over largely as is, or use the migration as an opportunity to redesign your information architecture. Lift and shift is faster and cheaper. Modernizing up front costs more time and money but avoids a second project down the road.
What happens to legacy customizations?
Every InfoPath form and SharePoint Designer workflow needs a decision: rebuild it in Power Apps or Power Automate, replace it with native Microsoft 365 functionality, or retire it if it no longer serves a purpose.
Phased rollout or a single cutover?
A phased approach reduces risk and lets you validate the process with lower stakes content first. A single cutover is faster but leaves less room to catch issues before your whole organization is affected.
How much training does your team need?
Even a clean lift and shift changes how people find and interact with content. Budgeting for training and a defined support window after go-live is what keeps a migration from generating a wave of support tickets.
Why a Foundational Migration Is Often the Right Starting Point
Not every organization needs a full modernization project on day one. For organizations with straightforward content environments, Compass365’s Foundational SharePoint Migration is built to get you to SharePoint Online quickly, reliably, and without unnecessary cost, while still leaving room to modernize later.
The approach covers:
- Assessment: a review of your current SharePoint configuration and content to build a risk-managed migration plan.
- Site build out: your new site is built to mirror your existing structure, with necessary modern enhancements layered in.
- Content migration: a two-step process that preserves metadata, permissions, and configurations.
- Validation and testing: user acceptance sessions confirm the new environment meets your operational needs before cutover.
- Cut-over: a final delta migration keeps downtime minimal.
- Training and support: role-specific quick guides plus two weeks of post-migration support.
It’s the right fit if you have low to moderate content volume with simple site structures, a tight timeline or budget, or an on-premises system you need to retire without a full modernization effort. It’s also a practical way to get off legacy infrastructure now and tackle deeper modernization on your own schedule.
