RMAN catalog Recreation Problems/Questions ....

!! Please do not post Off Topic to this List !!

Dear List Members,  

I have Production DB in 8.1.6.2.0(64bit) on one box, and RMAN catalog database
  (8.1.6.2.0) on another box. I need to upgrade both the DBs to 8.1.7.1.0. I have
  no problem upgrading the production DB to 8.1.7.0.0 and then to 8.1.7.1.0 patch
  level.

  The box on which catalog DB exists has another production DB which was upgraded
  to 8.1.7.1.0. and so I CAN NOT upgrade catalog DB to 8.1.7.1.0 using normal
  upgrade procedure. I must upgrade to base line release first(8.1.7.0.0) and
  then patch needs to be applied. Since patch was already applied, my only option
  could be to recreate the catalog database in 8.1.7.1.0 and then DO THE FULL
  IMPORT. My questions would be:

[1] Do I need to do the FULL IMPORT of the catalog database? and then
issue the
  "upgrade catalog" command twice to upgrade the catalog to work with the latest
  RMAN version? [OR]

[2] Do I just recreate the empty catalog DB in 8.1.7.1.0 and then follow
the
  regular procedure to create RMAN schema and register the DB and then take the
  fresh cold backup to start with, followed by the regular daily incremental

  backups?

[3]If I follow [2], I may loose the catalog info for 8.1.6.2.0. backups.
Is the
  8.1.6.2.0 catalog data useful after upgrading the DB to 8.1.7.1.0?

  Could some one please answer my above questions and suggest an appropriate procedure to
  upgrade the catalog DB to 8.1.7.1.0.

Thanks,
