Filesystems from those platforms are not cross-mounted either. This means that if you need to use data from another ECMWF platform such as ECGATE or the Cray HPCF, you will need to so transfer it first using scp or rsync. See Linux Virtual Desktop VDI: File transfers for more information.

If you port any scripts or code that had paths to filesystems hardcoded from older platforms, please make sure you update them. Where possible, try and use the environment variables provided, which should work on both sides pointing to the right location in each case:
