Hello,
we are under migration from one AS12772 to new one AS56341. Currently, in RIPE DB networks have route-objects with old AS12772.
Could you tell me when I need make changes (modify or remove/add) in RIPE DB: 1) add new route objects before migration and remove old after migration;
2) modify route objects after migration;
Hello Sergey, this is the right way to do it; this is called "make before break"; RPSL and the RIPE database support this by allowing route objects with different "origin:" for the identical prefix at the same time. that's "wrong" because this means that you create a time window during which your actual announcement is NOT documented/authorized by a matching route object. (Also keep in mind: route[6] objects use prefix AND origin AS as combined primary key. So two route objects with different origin: attribute should be considered fundamentally different. It may be correct to say "replace the route object".)
3) remove old route objects after migration and then create new objects. you would make the time window mentioned for 2 even longer
