Current environment

My understand overview

IFS Cloud i need to prepare new server 3 machine

1. Middle-tire server(Linux for install IFS cloud)
2. Management server(For prepare ifsroot,BuildHome and run script)
3. Database server( For install database)

Step 1. I need to upgrade oracle database from 11.2.0.1 to 19C

Step 2. After completed upgrade database i will prepare buildhome, script yaml file.

Step 3. After all script completed i have run “.\installer.cmd --values c:\exampletmp\config\ifscloud-values.yaml --values .\solutionset.yaml” command.

Remark :  - I'm not sure if the middle-tire server needs to be prepared somescript or not.
