CRM migrations and integrations that don't lose a record.

Almost always — but the customizations decide the effort, not the version number. We start with a drift analysis: your codebase diffed against the stock release, so we know exactly which files were modified and why. That audit tells us whether your migration is a weekend or a month before we touch anything. We wrote up the full process in our VTiger migration guide.

Data loss: no — we migrate a full copy on staging first and validate against a signed checklist before production is touched. Downtime: a short, scheduled window for the final cutover, with the old environment kept intact and ready for instant rollback during an agreed period.

Yes — we run self-hosted Mautic instances end to end: installation, cron and queue architecture, SSL, monitoring, tested backups, and updates applied with a rollback plan. Your team uses the tool; we own the 2AM pager. The operational side is detailed in our production Mautic checklist.
