Howdy folks,

  1. Hi.

    We’re using Mantis v1.1.6 now for a long time. Is it possible to install tha latest stable version (v1.2.3) without having the risk of loosing history?

    Thanks in advance and best regards,
    Michel van de Meent.

  2. Have the problems with upgrading Mantis 1.1.x to 1.2 on MSSQL databases been fixed?
