Older composition platforms are ageing
StreamServe, Documaker and older Exstream versions are costly to maintain. Consolidating on current Exstream cuts template counts and effort.

TechTiera implements OpenText Exstream, part of OpenText Communications, for statements, policies, letters and notices. We design templates, connect data sources, migrate legacy composition tools and run output operations.
