Upgrade From 5.01SE to 11.7

Hello All,

I am very new to this forum and I am well versed with DB2 and Oracle databases, but not with Informix.

So please do excuse me if this question has already been answered.

The problem is one my client wants to upgrade their database's from Informix 5.01se to the latest Informix 11.70 C-innovator version.

They want to have HDR along with it.

I have searched IBM redbooks and it seems that there is no direct upgrade path from 5.01se to 11.7 C-Innovator version.

Wanted to ask the learned folks here for any pointer or any information in regards to that.

Any help or pointers are much appreciated.

Thanks

Venkat
