As mentioned previously, we would like to consolidate the existing production servers (Sixtrack, vLHC and ATLAS) into a single service. We hope that by doing this we can improve the support and reduce the confusion. One benefit for all is that there will be a single forum so both us and our volunteer moderators can be more effective.
The transition will have two phases, commissioning and decommissioning. First a new server will be prepared with a similar configuration as this dev project but based on the Sixtrack DB. This is because they have the most users and 50% of the active users from vLHC and ATLAS are already there, hence it should minimize the impact. Once this new server is ready, it will be opened up for use in parallel with the existing three servers.
Next comes the decommissioning. For Sixtrack this should be straight forward, the URLs for the old host will be redirected to the new host. For vLHC and ATLAS things will be a little more complicated. Those users who are already registered with Sixtrack will be encouraged to move to the new server. For those who are not registered they can either register themselves and move or we can do a bulk registration. Tasks can then be stopped and the URLs redirected.
Finally there is the issue of credit. It should be possible to migrate the credit from the old servers to the new server. This can only really be done once the servers are no longer used. There is no time critical aspect, just until this is done, only the new credit will be seen.
Comments and feedback on this proposal are welcome.
P.S The dev project will stay around as it is.
