migrate 32 bit to 64 bit sql server

Pre Implementation Steps

Script out logins
Script out Linked Servers
Script out jobs
Take system database(master,model,msdb) Full Backup
Take user database Full Backup

Steps

Install new VM with Windows Server with required RAM and partition 4 drives as system and data/log and backup and tempdb
add hostname as newserver
Copy application files from oldserver to newserver
Install SQL Server 2016 Enterprise edition 64 bit  with latest SP(Service Pack) as per existing collation(Required collation)
Create logins from oldserver which we scripted out earlier
Create Linked Servers from oldserver which we scripted out earlier
Test Linked server connections
Restore user database from oldserver which we backedup
Restore msdb database from oldserver which we backedup would create jobs and schedules
Check jobs whether running or not
Configure DB mail and check connectivity
Test applications connections and functionality

Post Implementation Steps


Install ODBC/OLEDB Drivers for excel to be worked for import/export
Configure SQL Server memory as per RAM size
Configure Error log files
Create tempdb secondary files as per no of cores/processors
Configure SQL Agent history
Implementation of 32 bit to 64 bit SQL Server instance
Take Backup on system and user databases on oldserver
Stop SQL Services on old server
copy backup file  to newserver local
Restore user databases on newserver
change the IP/hostname from newservername to oldservername
restart server machine
verify hostname
Change SQL Service instance name from newservername to oldservername
Restart SQL Service
Verify SQL Server name
Check application connectivity and functionality
Check Report working fine

Waiting for SQL Server to recover database 'msdb' and SQLServerAgent is not currently running so it cannot be notified of this action. (Microsoft SQL Server, Error: 22022)

Impact:

SQL agent job shows next run column as not scheduled even if you run job it shows "SQLServerAgent is not currently running so it cannot be notified of this action"

but SQL configuration manager service status shows as running and mode is automatic


Sometimes you would get this error even if the SQL Server Agent is running. In those cases, you need to check SQLAgent.out file to check if it’s started
completely.

Solution:

Something SQLAgent.out file from E:\Program Files\Microsoft SQL Server\MSSQL14.InstanceName\MSSQL\Log


we can start SQL Agent services to fix this error.

Bulk load failed

Msg 5301, Level 16, State 1, Line 1

Bulk load failed. User does not have ALTER TABLE permission on table 'Table_2'. ALTER TABLE permission is required on the target table of a bulk load if the target table contains triggers or check constraints, but the  'FIRE_TRIGGERS' or 'CHECK_CONSTRAINTS' bulk hints are not specified. ALTER TABLE permission is also required if the 'KEEPIDENTITY' bulk hint is specified.

Issue:

While we perform Bulk insert operation on table it will through error as requires bulkadmin and alter table permission for user

When you use bulk insert on main table it ignores constraints and disables triggers.

https://docs.microsoft.com/en-us/previous-versions/sql/sql-server-2005/ms188365(v=sql.90)?redirectedfrom=MSDN

Permissions:

Requires INSERT and ADMINISTER BULK OPERATIONS permissions. Additionally, ALTER TABLE permission is required if one or more of the following is true:

·         Constraints exist and the CHECK_CONSTRAINTS option is not specified

·         Triggers exist and the FIRE_TRIGGER option is not specified.

·         You use the KEEPIDENTITY option to import identity value from data file.

https://www.red-gate.com/simple-talk/sql/learn-sql-server/bulk-inserts-via-tsql-in-sql-server/

• By default, the BULK INSERT statement ignores constraints and disables triggers.
• By default, the INSERT…INTO statement executes check constraints and triggers.

Fix for this issue:

We can create temp table first and use this temp table in bulk insert operation then we can get the row from temp table will resolve disable triggers and permission requirement on user.

   bulk insert Table_2 from  'D:\test.csv' with ( fieldterminator = ',', rowterminator='\n')

create table #temp(tid int,tname varchar(50))

bulk insert #temp from  'D:\test.csv' with ( fieldterminator = ',', rowterminator='\n')

insert into Table_2

select * from #temp
