You are moving mail from OVH to Proton, outside our packaged “all Infomaniak” path. InfoSwitch runs these programmes under the UEswitch line: technical analysis, controlled history copy, DNS and user support—with fees noticeably higher than standard Infomaniak migrations because each source/target pair needs bespoke scoping.
EU-to-EU provider change
From OVH to Proton: similar macro-region, yet different tooling, quotas and DNS. The priority is service continuity and clean history migration.
OVH specifics
You are leaving MX Plan, Email Pro or Hosted Exchange: we document quotas, aliases, rules and account types so Proton receives a faithful structure without losing critical folders or filters.
- Protocols — Classic IMAP or Exchange today; the target may require different client provisioning.
- DNS — MX/SPF/DKIM/DMARC readiness for the move to Proton.
Proton Mail target
Proton focuses on encryption and privacy: depending on the plan, official IMAP import tooling has limits (volume, Business features). We size a realistic path from OVH and set expectations (Bridge app, Proton clients).
UEswitch method (Proton)
Audit & inventory
Mailboxes, volume, aliases, critical rules and maintenance windows.
Target provisioning
Proton account creation, send/receive tests, folder plan.
Sync & deltas
IMAP copy (or adapted tooling), iterative passes, pilot sampling.
DNS cutover
MX, SPF, DKIM, DMARC; TTL reduction; coexistence if required.
Clients & hypercare
Desktop/mobile reconfiguration, internal FAQ, short project hotline.
UEswitch pricing
Cross-provider work needs more engineering than our standard Infomaniak migrations. Public Infomaniak-oriented pricing does not apply as-is: bespoke quotes, typically materially higher, scaled to volume and criticality.
Third-party brands
OVHcloud, Proton AG / Proton Mail are trademarks of their respective owners. InfoSwitch provides independent migration engineering services.
