The LHC performed extremely well in operation. Large amounts of data have been collected at a center-of-mass energy of 7 TeV in 2011 and at 8 TeV in 2012. Meanwhile, a phased upgrade of the LHC is planned and in about ten years from now the high-luminosity LHC (HL-LHC) is foreseen. By luminosity levelling and a ten times higher LHC design luminosity the delivery of about 3000 fb-1 is envisaged. To cope with the severe radiation dose and high particle rates, an upgrade of several detector components of the ATLAS and CMS experiments is required. The seminar will layout the planned upgrades of the inner tracking detectors. Focus will be given on the upgrade plans for silicon strip detectors in the ATLAS and CMS experiments for Phase-II. It will show an overview of the concepts and highlight technology choices for the upgrade strip trackers. The developments for the ATLAS detector towards low mass and modular double-sided structures for the barrel and forward region will be discussed and status of prototyping, assembly procedures and mechanical and electrical results will be presented.
