I plan to use ArcGIS Enterprise Builder (10.9.0) to install base deployment of Enterprise ArcGIS on a single server for production purpose. I already reviewed the related Esri links on ArcGIS Enterprise Builder. This post is trying to get feedback on potential problems and issues on using this installation methods. For example, is any problem for future version upgrade on this type of install ? My quick review already noticed certification issues reported by others. I would like to get more feedback before deciding if I need to go through this approach or to install each Enterprise component separately. Thanks for your help.
