I have been trying to use CWS to perform Category Upgrades. While this works perfectly, it is relatively slow as DocumentManagement.UpgradeCategoryItems only selects 30 items in each pass. I noticed that the Context.ChunkSize could be set and set this to 1000 with no effect. Does anyone know where the 30 item limit is set and if it is possible to change it? Additionally, is there a setting which can cause an upgrade to resume from where it left off? The upgrade appears to begin again, if stopped and restarted, even though the first part of its run will be for already upgraded items.
