IIS Migration

               IIS 6 to IIS 7 Migration

                   -----------------------------------------------

I have tested several migrations on our LAB servers with different versions

of web deployment tools and different methods as well, and finally

designing this migration document with combination of all method, and

helpful for team for real-time IIS migrations.

           *** IIS MIGRATION STEPS ***

1. Backup your source IIS server (IIS 6)

 In the IIS snap-in on the local computer, click the Computer icon under Internet

Information Services.

 Click Action and select Backup/Restore Configuration.

Click Create backup, choose a name for your backup file, and then click OK.

NOTE: If you wish to encrypt the backup set, place a check mark next to Encrypt

backup using password, and enter your desired password before clicking OK

2. Install web deployment tool on source server (IIS 6)

Download Web deploy tool based on OS type 32bit or 64 bit,

Refer URL'S below for downloading different web deploy versions.

Web Deploy 1.1 -- http://www.microsoft.com/en-in/download/details.aspx?id=24709 (X86 - 32 bit)

Web Deploy 1.1 -- http://www.microsoft.com/en-in/download/details.aspx?id=4148 (X64 - 64 bit)

Web Deploy 2.0 -- http://www.microsoft.com/en-us/download/details.aspx?id=25230

Web Deploy 3.0 -- http://www.microsoft.com/en-in/download/details.aspx?id=30436

Web Deploy 3.5 -- http://www.iis.net/downloads/microsoft/web-deploy

3. Check for all the dependencies installed on source Server

msdeploy -verb:getDependencies -source:metakey=lm/w3svc/1

Note -- Run above command from source server Msdeploy directory to check the dependencies

installed, /1 is website identity number and belongs to Default website, If you want to check

dependencies for all sites than remove /1 and run the above command without /1 or website

identity number

Once you run the above command it will display all the dependencies software installed E.g

Asp.net 2.0, 4.0 or any other dependent software or com files installed.

4. Backup the configuration of all websites on Source server

msdeploy -verb:sync -source:webserver60 -dest:archiveDir=<path to archive

to>,encryptPassword=<password> -disableLink:contentExtension

Note -- Do not change 'webserver60' to different server name, It is used as sync and need to use

as it is. This will create your IIS website configuration and data backup in XML format.

5. Install IIS 7.0 / 7.5 on destination server

Note -- Install IIS (7.0 or 7.5) on destination server, Refer link below for installation steps

http://www.iis.net/learn/install/installing-iis-7/installing-iis-7-and-above-on-windows-server-2008-or-windows-server-2008-r2

After IIS installation installed all the dependency software's found as per Step 3

( E.g .net 2.0, 4.0 etc)

6. Backup your destination IIS server ( IIS 7, 7.5)

To back up the IIS 7 configuration from a command prompt

 Log on to the Windows Server 2008 with an account that has administrator rights.

 Open a command prompt by using the Run as Administrator option and change

directory to %windir%\system32\inetsrv.

 At the command prompt, type appcmd add backup <backupname>. If you do not

include the name of the backup, the system will name it for you by using a date, time

format.

7. Install web deployment tool on Destination server (IIS 7)

Download Web deployment tool based on OS type 32bit or 64 bit,

Refer URL'S from step 2, for all Web deployment versions.

Note – Make sure your account has administrator rights while installing web deployment.

8. Copy the XML configuration files created from source to

destination server

Note – Copy .xml files created as per step 4 from source to destination server

9. Restore configuration files on destination

After all files were in place on the new server, run below command to restore IIS 7 with the

configuration

msdeploy -verb:sync -source:archivedir=<path to

archive>,encryptPassword=<password set in previous command> -dest:webserver60

Note -- Do not change 'webserver60' to different server name and used the same

encryptPassword set in source server while creating a XML configuration file. , Above command

will create all sites on your destination IIS server and also set the web content path for all the

sites, It is also observe that while using some of the lower webdeploy version webcontent

directory was not moving to destination server in such scenario used following command to copy

the webcontent directory from source to destination server, this will copy the webcontent

directory and keep all the permissions intact.

Copy webcontent folder along with all sub folders from source to destination using XCopy command

xcopy <source path> <destination path> /O /X /E /H /K

10. Check destination IIS server to confirm all the IIS sites

were created

Test all your migrated website status, Possibly you need to check the application pool settings

and correct the permissions and application pool if require. Check for SSL certificate Bindings and

assign the certificate for website, if it is not bind properly with website after migration.
