Blog 1.7.5016.2 has been released!

Those who have earlier versions can update their versions to 1.7 X now.
You can download the files from https://sourceforge.net/project/showfiles.php?group_id=127624.

Now how to upgrade the blog without any data loss. Upgrading from versions earlier than 1.7.5016.1.

Download these files from the above url.

• Download the dasBlog-1.7.5016.2-Web-Files.zip
• Download the dasBlog-1.7.5016.2-Upgrader.zip

Now let us see the steps how to upgrade.

Download your blog first and zip it as backup and also ensure -you have taken backup of your content, siteconfig,logs folders and web.config file, which carries your blog contents and config information.

Copy the Unzipped Dasblog 1.7 web files into the path.Copy the content, siteconfig,logs folders and web.config file from the backup to this folder.

Now run the dasblogupgrader.exe against your content folder.
Example : c:\dasblogupgrader.exe "D:\webistes\myblog\content"
BACKUP YOUR CONTENT FOLDER BEFORE RUNNING THIS!
Press ENTER to Continue...

Enter...

1. Make sure that all the entries are in the correct dayentry files. Some version of dasBlog placed them in the wrong files. This works by loading all your entries, backing up the old files in content\backup folder, and rewriting all the entries from an in memory cache.
2. Upgrade all the dayextra files because of a change in the file name to be a UTC file name (same as dayentry). The mismatch before caused some referrals, trackbacks and pingbacks to be lost due to the fact that dasBlog was using the UTC date of the dayentry file to look for the dayextra file and this resulted in no file found in many cases.
3. Set the IsPublic field on a all entries to true. dasBlog 1.7 finally uses this field to hide entries from everyone except the admin or any other authenticated users.
4. Delete any referral spam from your dayentry files (now named dayfeedback) using the keywords found in the DasBlogUpgrader.config file and entries in the MovableType Blacklist.

At this point you should have a local copy of all the dasBlog files needed, with your upgraded content folder, as well as your SiteConfig folder, and Web.config.

Now copy the files to your blog

1. Make sure on the server to delete the following
   1. Delete the contents (not folders) of bin, content, logs, SiteConfig. Do not delete themes
   2. Delete the folders ftb, images.
   3. Delete all the files in the root web application (.aspx files, asmx files etc).
2. Copy the contents of your Unzipped Dasblog 1.7 web files to your remote server. Do not overwrite your logs folder.

Check: If you are running IIS 6 you must give NETWORKSERVICE the same permissions as ASPNET

Success!!! Now you are in to blog new version. Ensure the version newtelligence dasBlog 1.7.5016.2
