I don't get the reason for 10 hour maintenances that stretch till 11pm at night... you'd think everything would be prepared on a test server prior to implementation, and maybe an hour or two to double check for bugs. At this rate, Thursdays are basically "you can't play" days for all EST players.

During the maintenance the game will be moving to newer servers. We expect this to add extra time to the maintenance due to the need to transfer the data. This means that today's client patch cannot be skipped. 

 

 

this response seems to imply that these kind of all-day maintenances aren't a frequent occurence, even when server migration isn't happening. 

[ragnadood2003]

As someone who has worked in IT for years building and maintaining servers for companies, I can tell you this: if the server migration involves moving the server data to a new storage device, copying files can only go so fast. I've had migrations where a company bought a new SAN and we had to copy the data over the network from the old storage array to the new one. Multiple terabytes of data can take many, many, many hours to move. If you are working with tons and tons of tiny files, it could even take multiple days to move if you are verifying the data once it gets to the new storage device.

 

Having a test server in cases like that really just gives you a pretty good estimate of how many hours you are going to be waiting for the data migration to finish. It won't speed up the copy process of all the production data you still have to move.

 

So yes, an extended maintenance for a server migration is not an unreasonable expectation.

there is no reason the server files couldn't have been copied in preparation, and then copy only the player data files on the day of maintenance. player data is miniscule and copying all the millions of accounts shouldn't take more than a few hours at the utmost.

You can't copy ever-updating data in preparation. You need to stop the server to be able to copy the events without having any rollback of anykind. Imagine getting a super rare card but then its gone because the last save was done before you gotten it?

Any ETA?

[Campitor]

testing is all going good. Working on bringing up chaos then we will open. It may be a little time due to the need to copy 19,000 guild emblems.

File locking prevents doing something like this. If a file is currently in use by a process that won't let it go, you cannot copy the file at the same time. This is especially true with databases - SQL Server databases are two files, a data file and a log file. If SQL Server is running you cannot just 'copy' the two files. It doesn't really work. You can make a backup and move it, but the file begins to age as soon as the backup finishes if the original is still in production use. And because the databases are just two files, moving just the records that have changed after the backup isn't as easy as it sounds without a record comparison.

 

As I know from lots of experience, the goal of server maintenance is always to minimize downtime, but some things you just can't avoid and they do take time to complete correctly. Migrating from one server to another is one of those things you just have to set aside time for unless the application was written in such a way to make it migration proof.

 

Trust me, there are very few applications that are designed that way...
