I'm slightly confused because the subject of your post mentions the "Informatica Adapter" and "solution bridge".
If you are currently using the Informatica Bridge (tdlbdginfa86) I do not believe it supports 9.1.x and above (I didn't even realize is supported 9.0.1). The good news is the license for the Bridge can be carried over to the Infomatica Adapter (no additional cost, confirm with your sales rep). The bad news is there is no tool to migrate your Tidal jobs from the Bridge to the Adapter. It has to be done manually.
You will need to install the Informatica Adapter connecting to the 9.0.1 version, manually migrate all jobs to the Adapter, then upgrade Informatica.
Thanks.

Good luck.
