WebSphere ND Migration 7.0 to 8.0 / 9.0 on Same Machine.

Prequesties check:
1. Check O.S prerequisites.
2. Source WAS 7.0 should be completely stopped.
3. Disk space needs to be there. 
4. Targeted WAS 8.0 / 9.0 needs to be installed on a machine.
5. Increase the number of open files limits on the O.S level (ulimit -a).


Tools for Migration
a) Migration 9 GUI based (WCT tool).
b) Command-line (i) WASPreUpgrade (ii) WASPostUpgrade


I have three profiles in existing WAS 7.0(in my scenario), 
a) Dmgr01
b) Custom01
c) Custom02

NOTE: Before proceeding always take config or profile backup.


*****************************************************************************************************
Commands for backup.

a) Dmgr01 backup

Command:
./backupConfig.sh /app/WAS7-APP-ND/IBM/WebSphere/AppServer/profiles/Mig-Backup_Dmgr01.zip   
-profileName Dmgr01 





 b) Custom01 backup

Command:
./backupConfig.sh /app/WAS7-APP-ND/IBM/WebSphere/AppServer/profiles/Mig-Backup_Custom01.zip   
-profileName Custom01 







*****************************************************************************************************

  • Install New instance of WAS 8.0 / 9.0 on Machine.
  • IMP NOTE: Before proceeding, need to create the same profiles in WAS 8.0 / 9.0  with having the same nodeName, cell namehostname, servers instances & no applications.

*****************************************************************************************************

A) create the same profile "Dmgr01" in WAS 8.0 having same nodeName, cellName,  hostname , server instance & with no applications.

Command:
/app/WAS8-APP-ND/IBM/WebSphere/AppServer/bin/manageprofiles.sh -create   
-profileName Dmgr01 
-profilePath /app/WAS8-APP-ND/IBM/WebSphere/AppServer/profiles/Dmgr01   
-templatePath /app/WAS8-APP-ND/IBM/WebSphere/AppServer/profileTemplates/management   
-serverType DEPLOYMENT_MANAGER   
-nodeName Dmgr01Node  -cellName Dmgr01NodeCell -hostName MBox  -defaultPorts 
-enableAdminSecurity true -adminUserName was -adminPassword was123




B) create the same profile "Custom01" in WAS 8.0 / 9.0 having the same nodeName, cellName,  hostname, server instance & with no applications installed.

Command:
/app/WAS8-APP-ND/IBM/WebSphere/AppServer/bin/manageprofiles.sh -create  
-profileName Custom01 -defaultPorts  
-profilePath /app/WAS8-APP-ND/IBM/WebSphere/AppServer/profiles/Custom01  
-templatePath /app/WAS8-APP-ND/IBM/WebSphere/AppServer/profileTemplates/managed  
-nodeName Custom01Node  -cellName Custom01Cell  -hostName MBox -federateLater true





*****************************************************************************************************


Create a folder on targeted WAS 8.0, to place WASPreUpgrade migration command files.

Command:
mkdir -p /app/WAS8-APP-ND/IBM/WebSphere/WASMigration/Dmgr01
mkdir -p /app/WAS8-APP-ND/IBM/WebSphere/WASMigration/Custom01
mkdir -p /app/WAS8-APP-ND/IBM/WebSphere/WASMigration/Custom02












WASPreUpgrade 

  • NOTE: Stop all the WAS services on 7.0.
  • Run WASPreUpgrade command from WAS8-APP-ND/IBM/WebSphere/AppServer/bin/ for "Dmgr01" profile.


Command:
/app/WAS8-APP-ND/IBM/WebSphere/AppServer/bin/WASPreUpgrade.sh   
/app/WAS8-APP-ND/IBM/WebSphere/WASMigration/Dmgr01  
/app/WAS7-APP-ND/IBM/WebSphere/AppServer/    
-traceString Migration.Flow=finer:Migration.*=fine   
-traceFile /app/WAS8-APP-ND/IBM/WebSphere/WASMigration/Dmgr01_WASPreUpgrade.trace  
-oldProfile Dmgr01   -username was   -password was123

Similarly  

  • Run WASPreUpgrade command from WAS8-APP-ND/IBM/WebSphere/AppServer/bin/ for "Custom01" profile.

WASPostUpgrade 
  • Run WASPostUpgrade command from WAS8-APP-ND/IBM/WebSphere/AppServer/bin/ for "Dmgr01" profile.

*****************************************************************************************************


IMP NOTE:
Start the Dmgr01 profile, and force delete the already federate nodes in dmgr from DMGR console.
Since it contains WAS 7.0 node agents.







  • Run WASPostUpgrade command from WAS8-APP-ND/IBM/WebSphere/AppServer/bin/ for "Custom01" profile.


Command:
 /app/WAS8-APP-ND/IBM/WebSphere/AppServer/bin/WASPostUpgrade.sh  
/app/WAS8-APP-ND/IBM/WebSphere/WASMigration/Custom01  
-oldProfile Custom01  -profileName Custom01 -scriptCompatibility true   -replacePorts false  
-includeApps true  -keepAppDirectory false  
-traceString Migration.Flow=finer:Migration.*=fine 
-traceFile /app/WAS8-APP-ND/IBM/WebSphere/WASMigration/Custom01_WASPostUpgrade.trace -username was   -password was123


NOTE: The above command will automatically federate the node, with the running Dmgr01 profile.







For understanding.
  1. stop WAS 7.0 services & profiles completely.
  2. take existing WAS 7.0 Backup.
  3. install WAS 8.0 and create same profiles on new WAS 8.0 /9.0 , having same nodeName, cellName,  hostname, server instance & with no applications.
  4. Run $WAS8_HOME/bin/WASPreUpgrade command, & save the pre upgrades migration files.
  5. Run $WAS8_HOME/bin/WASPostUpgrade command & for Dmgr01.
  6. Start WAS 8.0 Dmgr01 and force delete the nodes of WAS7.0
  7. Run $WAS8_HOME/bin/WASPostUpgrade command for Custom01, (it will automatically federate the nodes with WAS8.0 dmgr01)
  8. Do the same for Custom02 also.
  9. Clear all profiles wstemp, temp, tranlog & logs files.
  10. federate the nodes with dmgr and start node & servers instances.

Openssl Self-Signed SAN's certificate

Step 1: Create a file san.cnf file and add below content to it.

########################Create a file san.cnf file################

[ req ]
default_bits        = 2048
distinguished_name  = subject
x509_extensions     = x509_ext
string_mask         = utf8only

# The Subject DN can be formed using X501 or RFC 4514 (see RFC 4519 for a description).
#   Its sort of a mashup. For example, RFC 4514 does not provide emailAddress.
[ subject ]
countryName         = Country Name (2 letter code)
countryName_default = IN

stateOrProvinceName         = State or Province Name (full name)
stateOrProvinceName_default = MAH

localityName          = Locality Name (eg, city)
localityName_default  = MUM

organizationName         = Organization Name (eg, company)
organizationName_default = MBOX

# Use a friendly name here because it's presented to the user. The server's DNS

commonName          = Common Name (e.g. server FQDN or YOUR name)
commonName_default  = www.MBbox.com
emailAddress         = middlewarebox@gmail.com

# Section x509_ext is used when generating a self-signed certificate. I.e., openssl req -x509 ...
[ x509_ext ]

subjectKeyIdentifier    = hash
authorityKeyIdentifier = keyid:always,issuer:always
basicConstraints       = CA:TRUE


#   omit keyEncipherment because that's key transport.
keyUsage          = digitalSignature, keyEncipherment
subjectAltName    = @alternate_names
nsComment         = "OpenSSL Generated Certificate"


[ alternate_names ]

DNS.1       = www.mbox123.com
DNS.2       = middlewarebox.com
DNS.3       = www.qwerty.com

###################################################################




Step 2: Use below the below command.

Command:
export OPENSSL_CONF=/etc/httpd/conf.d/san.cnf





Step 3: Below command and press enter till exit.
command:

openssl req -x509 -sha256 -nodes -days 1365 -newkey rsa:2048 -keyout privateKey.key -out certificate.crt





Step 4: Add these generated  Keyfile & certificate location  in apache-web (ssl.conf) file.





Step 5: Check from browser






Installation Manager (IM) on non-Administrator user.

What is IM?
Installation Manager is a tool that you can use to install and maintain your IBM software packages. 
The following steps can perform the install, modify, update, rollback, or uninstall your IBM products.


Step 1: Extract IM setup.

Step 2: Locate to $IM_SETUP/userinstc script for Installation using for command method.

-dataLocation /IBM_WAS/IBM/IM_logs 
-showProgress


Where,
userinstc: To install silently (non-administrator) script for installation.
installationDirectory: Installation directory location.
record: To record installed steps.
dataLocation: For IMP installation Manager logs.
showProgress : For installation status.



Step 4: To check the installation location.
