Using the Migration Tool

The IHA Migration Tool (MigrateIHA.exe for 32 bit or MigrateIHA_x64.exe for 64 bit) allows you to migrate data up to 30 years old if the data is already stored in IHA files from any version of Historian. Use the Migration Tool to move data from one archiver to another when you cannot simply restore the IHA in the Historian Administrator.

The Migration Tool opens an IHA file as a binary data file and reads the raw samples from it. Those raw samples are then written to a destination archiver, in a similar way to how an OPC collector or File Collector would write data. Any errors returned from the data archiver are reported in the main window and repeated in the log file.
