These guides describe the recommended method for transferring CostsMaster to a different PC. There are separate guides for transferring CostsMaster 2 and CostsMaster 3 as the procedures differ slightly.
If you are transferring both versions we would recommend that you follow the instructions for transferring CostsMaster 3 first, as the Backup Settings function in version 3 will also backup any CostsMaster 2 settings. You can then skip this step from the CostsMaster 2 instructions.
