Oracle upgrade from 11 to 19



we are planning to migrate our ECC6.0 EHP4 system from current AIX environment to X86 platform, at mean time, upgrade oracle from 11.2 to oracle 19. database size now is more than 10TB, since downtime is quite critical for us, therefore export and import is not possible, do you have any suggestions how we can achieve this and reduce downtime to minimum? thanks a lot.

Requirements are:

1. Migrate 15TB ERP system to X86 platform new hardware

2. OS change from AIX to Linux (maybe Redhat 8)

3. DB: Oracle upgrade from to 19 (maybe 19.8)

4. Downtime minimum

any comment is appreciate.

Best regards,
