Move DB to new server

[sgwisby]

We moved our db to a new server and when I try to look at the parameters for the DB(RMAN Catalog and Target DB) I get the error:
'RMAN 06004: Oracle error from recovery catalog databse: RAMN 20011, target database incarnation is not current in recovery catalog.'
Does this mean I need to re-sync the db using the following command:
SQL "ALTER SYSTEM CHECKPOINT";
ALLOCATE CHANNEL FOR MAINTENANCE TYPE DISK;
CHANGE ARCHIVELOG ALL CROSSCHECK;

And if I run this command, is it disruptive?

Thanks
