As we have already mentioned in our recent workshops the MOS Note:1389592.1 is public now:
- MOS Note:1389592.1
Reduce Transportable Tablespace Downtime using Cross Platform Incremental Backups
This technique currently works for migrations to Linux64 and is supported by Oracle Support for Exadata migrations only. It utiliuzes RMAN incremental backups to reduce the large amount of downtime it takes to copy and convert the datafiles cross Endianness.
Two requirements must be met to use this new functionality:
- Oracle 18.104.22.168 plus Exadata BP12 (patch 12982245)
- One-off patch 13340675 contains the RMAN extension and is currently available on top of BP12 on Oracle 22.214.171.124
Let me know if you have further questions – and this restriction on Oracle 126.96.36.199 with BP12 applies to the intermediate instance you’ll use to roll forward your converted incremental backups only. Source might be Oracle 10.2 whereas target might be also an Oracle 188.8.131.52 installation.
