I’ve been using 951G-2HnD for several years now, excellent product. Recently I got my hand on the newer RB962UiGS-5HacT2HnT.
Question is simple. Is there an “easy” way to migrate all config from old to new mikrotik?
Specifying both verbose and compact makes no sense. The default for the last couple of years has been compact so /export file=somename should be sufficient.
Make sure the target device has no configuration at all or the import will likely fail due to conflicts. With different models there may be some incompatible differences - if this is the case you can either fix the offending statement in the export and import the file again starting at the failed line, or remove the problematic statements and fix the configuration after the remainder of the configuration has been imported.
Or better yet: start configuring the new device from defaults and only change or add settings needed. And try to stick to new way of configuring it. Chances are that RB951 setup still contains remains of ancient defaults which were very likely far worse than current ones. Or contains some unnecessary bloat which used to be recomended here and there.
