Migration guide
OceanLog is legacy. Rescue the dives.
OceanLog is the old Oceanic desktop software, tied to a serial interface and a version of Windows most people no longer run. Divers find it when they dig out an old computer and want the history off it before the battery goes.
Move your dives, step by step
If OceanLog still runs, export your logbook to whatever open format it offers.
If it does not, connect the computer to a desktop with its interface cable and download it with Subsurface, then export UDDF.
Move the exported file to your phone: AirDrop, iCloud Drive or email all work, anything that puts it in the iOS Files app.
In SeaLog, tap the plus button, then Import dives, then the matching format.
Pick the file. Every dive arrives with its depth profile, and anything already in your logbook is skipped rather than duplicated.
These interfaces are USB-to-serial and need the driver for their chipset, usually Silicon Labs CP210x or FTDI. Install the driver before blaming the cable.
What survives the move
✅ Comes across
- Date, time, duration and maximum depth
- The depth profile, when the source carries samples
⚠️ Does not
- OceanLog's own equipment records
Whatever comes in can go back out: SeaLog exports the whole logbook to UDDF, CSV or PDF at any time. We would rather you could leave than have to trust us.
Read your computer directly instead
If the software is the broken part, going straight to the hardware is often faster.
Questions
The computer is twenty years old. Is the data still there?
Usually yes, until the battery dies. That is the argument for doing the download this month rather than next year.
Your dives, on the phone that is already in your pocket
Free to download, offline first, and every dive exportable the day you decide to leave.
