During a migration you run both environments at once — old and new storage, compute, and licenses — and you pay for the overlap every day it drags on. A slow mover stretches that window for weeks. See what cutting it to days is worth.
The window is the transfer time; double-running cost is your daily spend on keeping the old and new environments live in parallel (storage, compute, licenses, staff). Estimates assume your storage and hosts can sustain the link — Zettar realizes ~90%+ of it. Get an exact migration plan for your environment →
Zettar — Migration-window business caseWhat Zettar returns: a cutover measured in days instead of weeks — less double-running, staff freed sooner, and a lower-risk migration. Proven: 1 PB in 29 hours at 96% utilization with SLAC and the U.S. DOE.

Until the last byte lands and you cut over, the old environment keeps running beside the new one — and you pay for both. A mover that fills 10–30% of your link turns a one-day move into a multi-week overlap. Zettar runs at line rate, so the window collapses and the double-running stops.
It is the transfer time for your data over your link at each tool's realized utilization — Zettar at line rate (~90%) versus your current tool. The cost is that window multiplied by your daily double-running spend (keeping the old and new environments live in parallel).
Because until the last byte lands and you cut over, you run both environments at once and pay for both — storage, compute, licenses, and staff. A mover that fills 10–30% of your link stretches a one-day move into weeks of overlap. Zettar collapses the window so the double-running stops sooner.
Yes — it builds a one-page business case you can download or print, with your data, link, window, and the double-running you avoid. Book a demo for a measured migration plan on your environment.
