[BlueOnyx:23032] Re: "Easy Migrate" released \o/

[Colin Jack]

Hi Michael (and team),


    Hi all,
    
    Have you recently cursed at CMU? When it botched up another migration?
    You still can! But only if you want to.
    
    But there is a new kid in town and it's name is "Easy Migrate". I'd like
    you to get to know him, because once you do, you wish you had known him
    sooner. (Sorry, my fault! Should have coded it sooner.)
    
    If you want to jump right at it, the documentation for "Easy Migrate"
    can be found on our newly overhauled BlueOnyx.it website at this URL:
    
    https://www.blueonyx.it/easy-migrate
    
    That explains how "Easy Migrate" works.
    
    Easy Migrate is available for BlueOnyx 5209R and the latest YUM update
    should have brought it aboard automatically. You can find the command
    under /usr/sausalito/sbin/easy-migrate.pl
    
    Just run it with the "-h" parameter to see the available options.
    
    Easy Migrate works in a "pull" fashion. So you run it on the 5209R that
    you want to migrate to. It connects to the source server via SSH (SSH
    key exchange for user "root" is needed) and copies a helper script to
    the source server. That helper script gathers all the relevant
    information and reports it back.
    
    Easy Migrate can migrate the following:
    
    - Server configuration
    - MySQL
    - DNS
    - All Vsites and their Users
    - Reseller accounts
    - Configuration of installed WebApps and their data
    - Configuration of PKGs from the shop
    - Retains Vsite group names if they're free on target server.
    
    It runs CCE CREATE transaction to create all the CODB objects and also
    compares keys of CODB Objects and NameSpaces to make sure that he CREATE
    transactions don't try to set deprecated or absent keys.
    
    If the target server already has the Vsite that you're trying to migrate
    (from a previous CMU or Easy Migrate run), then it will use SET
    transactions to synchronize the settings between source and target server.
    
    For the transfer of files and folders Easy Migrate uses RSYNC over SSH
    and will make any necessary path adjustments on its own. During the
    RSYNC it will also directly adjust the UID/GID of files and folders to
    the required ones.
    
    MySQL databases and MySQL users that belong to a Vsite that's being
    migrated are also imported - as well as DNS records associated to a
    Vsite. This also includes secondary DNS and modifications in DNS include
    files. Optionally you can also import all MySQL and DNS data separately
    via Easy Migrate.
    
    Users that are migrated will also retain all their settings, files,
    emails and (if they have any) their user owned cronjobs.
    
    Easy Migrate can therefore be used to migrate individual Vsites and
    their Users, or all Vsites. But it can also be used to duplicate or
    clone Vsites or whole servers. As the file transfers are done via RSYNC
    actual synchronizations of Vsites and Users that were recently migrated
    already is much faster than a new migration.
    
    Easy Migrate can import from 5207R and 5208R to 5209R or 5210R. It can
    also do 5209R -> 5209R or 5210R -> 5210R or 5210R -> 5209R migrations.
    That way it supports all currently supported BlueOnyx versions as well
    as the upcoming 5210R.
    
    Imports from not yet updated 5107R/5108R are also possible, but for best
    results you should YUM update them first to turn them into 5207R/5208R.
    
    Does it actually work well? I suggest you try for yourself and report
    back and issues you find. I did a lot of testing and migrated several
    5208R production boxes to 5209R recently as well as shifted some Vsites
    around between servers. Any bugs I found myself during that are already
    fixed, but depending on your setups you might find the odd problem or
    glitch here or there. If you do, please let me know.
    
How cool is that! 
I will start 'playing' with some dummy sites ... but it sounds absolutely brilliant.

Thank you.

Colin
