Hello,

  I want to replicate the steps displayed in Studio during the upgrade/uplift process programmatically, but the API documentation is not very helpful on this.

  After a little bit of trial and error with the actual methods offered in the Sdl.LanguagePlatform.TranslationMemoryApi dll for Studio 2019, I have come up with the following rough code. It seems to do the job for file-based TMs but I want to be sure there are no undesired side-effects.

  Could somebody at SDL please confirm if these steps correspond to what the Upgrade Translation Memory command in the Studio application does?

private static void UpliftTM(FileBasedTranslationMemory tm)
{
    if (TranslationMemoryUpgradeUtil.TranslationMemoryRequiresUpgrade(tm))
    {
        TranslationMemoryUpgradeUtil.UpgradeTranslationMemory(tm);

        var token = new System.Threading.CancellationTokenSource().Token;
        var progress = new Progress<int>(i => { });

        if (TranslationMemoryUpgradeUtil.TranslationMemoryRequiresReindex(tm))
        {
            tm.SelectiveReindexTranslationUnits(token, progress);
        }
        if (TranslationMemoryUpgradeUtil.TranslationMemoryRequiresModelRebuild(tm))
        {
            tm.BuildModel();
        }
        if (TranslationMemoryUpgradeUtil.TranslationMemoryRequiresAlignment(tm))
        {
            tm.AlignTranslationUnits(true, false, token, progress);
        }
    }
    if (tm.ShouldRecomputeFuzzyIndexStatistics())
    {
        tm.ClearFuzzyCache();
        tm.RecomputeFuzzyIndexStatistics();
    }
    tm.Save();
}

Thanks,

Attila
