Want to migrate the database (4node RAC) size of 4 TB of 10.2.0.5 at 11.2.0.4 on the new servers where the new type servers Primary (4 nodes) and Eve (4 nodes).

Want to migrate the database (4node RAC) 4 TB size of 10.2.0.5(8 rompt = 4 prim/4 veille) to 11.2.0.4 on the new servers where the new type servers Primary (4 nodes) and Eve (4 nodes).  So with minimum downtime I have restore and recover again on 11.2.0.4 server must then clone that to create the day before.   Here, my question is can I take 0 backupp level before hand and restore on target (new) then primary at the time to leave the downtime take backup of level 1 of 10g and then retrieve it on 11g (new server) after successful recovery I'll perform clone to form eve of database on the new server. does this strategy work? If it works, can someone suggest me steps how can I need recover with backup after restoring the backup of level 0 on 11g. Like should I upgrade before you retrieve it with level 1 backup or I can update and then recover with the level 1 backup from the old server to the new server.

Here is former servers of RHEL 5 version and new servers are RHEL 6 release.

1 backup L0

2 restore L0

3. L1 and ArchiveLogs database backup

4. copy BackupPieces L1 and ArchiveLog BackupPieces on new server

5 CATALOGUE START WITH... to catalog the BackupPieces

6. TOGETHER until lastavailable SNA / Archivelog + 1

7 RECOVER DATABASE (should automatically identify the L1s and to apply ArchiveLogs)

8 STOP

9 START UPGRADE

10. run catupgrd.sql

You should also take care on the locations of the data file, dump, instance settings destinations, all link database from the database, connectivity application etc.
