The first installment of C9 v5 is now finally here.

To upgrade from v4 to v5. Do the following:

1. Make sure running latest v4. Main -> check for updates
2. After latest update is in then click on Main -> install v5.  It is best to do this on server computer as doing upgrade there will run faster.
3. Click through the screens until it completes. C9 will stop and start a couple of times during this
4. All done

A couple of notes.

Time to upgrade upgrading to v5 can take a long time especially if you have been using c9 for a while. If your c9 has a couple of decades worth of data in it and your server computer is a bit on the old side, low RAM and doesn't have SSD drives in it, upgrade will take about 30 minutes. So best left for end of the day. Newer systems with only 1 or 2 years worth of data, upgrade will take about 2 minutes.

In case of error The upgrade process is complex and there is a risk it might not work. If your upgrade doesn't work c9 will automatically revert back to v4.If this happens to you, let us know and we will investigate further and tweak the upgrader to work for you.
