If any migration failure occurs, this will be noted in the report. You should report any migration failures to your support channel. In some cases it may be necessary to modify this part of the station manually, and your support channel should be able to help with that.

The migration tool attempts to recompile all Program objects in the station with the new modules. In some cases, this may not be successful. Programs that cannot be compiled will be noted in the report, and you will need to modify the program manually to allow it to compile.

Station components whose type or module does not exist in N4, and for which there is not a type to migrate to, are removed. This should not occur frequently, as the modules that were removed for N4 were generally unused or deprecated modules.

If you find that a component has been removed that should not be, please report this to your support channel, as it may be that a converter needs to be developed for that type.

These messages are included in the migration report prefixed by “WARNING” or “SEVERE”, as appropriate. They indicate a more significant issue, likely a problem with the tool execution. You should inspect items referenced in such messages to make sure migrated artifacts are what you want.
