migrating a 32 bit system to 64 bit RRS feed

  • Question

  • hello -  i have few question regarding migrate from 32 to 64 bit.   my environment consist of 1 web server windows 2003 and 1 database server sql 2005.   i need to upgrade to 2010 and trying to find the best approach. 

    some questions. 

    1) can i migrate from 32 bit moss2007 to 64 bit sharepoint 2010?   or do i need to go from 32bit moss2007 to 64bit moss2007 first??

    2) can i backup the content database and configuration databases from sql2005 32 bit and then restore them to a sql 2008 64 bit? 


    i have read through the 'migrating an existing server farm' document here and still a little confused.  t hanks

  • You cannot "upgrade" 32 to 64 bit, you'll need to moved the databases to a new SP2010 farm using the attach database method. 

    That doc references WSS3, you mention MOSS2k7, and I assume you're going to SP2010 server not foundation? Check out, loads of references

  • thanks, its moss 2007.    web front end is on a 32 bit win2003 server.    sql server 2005 32 bit on a 32 bit server.   trying to get an idea of steps needed.   can you tell me if this looks ok:

    -set up 64 bit windows 2008 servers for web and database server

    -detach dbs from farm

    -backup sql server 2005 databases and restore to 64 bit sql server 2008.     this converts the 32 bit databases to 64 bit correct?

    -connect databases

    -install sp2010 to web server.    run configuration and connect to sql 2008?


    or do i migrate database first.     then install moss 2007 on 64 bit servers?  and the do an inplace upgrade?

  • Chan,

    Since you already have 64bit hardware for SP 2010. No need to go through inplace upgrade. You can migrate the content databases and use the database attach method. You will be creating a new Configuration database here.

    Don't forget to run the preupgradecheck before you start with the upgrade procedure.
