Migrating from 8.1.7 to 9.2 with different character set
Are there going to be issues when I try to migrate from 8.1.7 to 9.2 where the character set in the 8i database was the default western european to utf8 in 9i?
I ran the 8i scan utility to see if there would be issues importing into an 8i db with a different char set and it said that there would.
Hi Jim,
As your first step, I would recommend reading the white paper Character Set Migration Best Practices for Oracle9i on the Globalization Support Home page - http://otn.oracle.com/tech/globalization/index.html
Since you mentioned that CSSCAN has already reported there are potential issues (I guess you have exceptional/Lossy data ?), I would strongly recommend splitting up the UTF8 character set change and the database version upgrade into 2 distant phrases. Probably moving to UTF8 in 8.1.7 first, then upgrading to 9.2 later.
BTW, there is a separate Globlization Support and NLS discussion forum on OTN for further discussion on character set related issues.

How to export and import from AIX to solaris a whole schema with different
how to export and import from AIX to solaris a whole schema with different character set
import done in US7ASCII character set and AL16UTF16 NCHAR character set
import server uses WE8ISO8859P1 character set (possible charset conversion)
Import terminated successfully with warnings.The conversion between the character sets on the two servers are handled automatically. Export from one server will export the data given the character set defined on that server. Import into another server will import the data given the character set defined on that server, performing a conversion if necessary. This can be a problem when going from single-byte to a multi-byte character set. In your case, the warning is simply for your information, shoule be no real problem given the character sets you're using.
For more info...check out (pertains to 9i):

We are getting ready to migrate from server core 2008 r2 hyper-v with failover cluster volumes on an iscsi san to server core 2012 r2 hyper-v with failover cluster volumes on a new iscsi san.
I've been searching for a "best practices" article for this but have been coming up short. The information I have found either pertains to migrating from 2008 r2 to 2012 r2 with failover cluster volumes on the same hardware, or migrating
to different hardware without failover cluster volumes.
If there is anyone out there that has completed a similar migration, it would be great to hear any feedback you may have on your experiences.
Currently, my approach is as follows:
1. Configure new hyper-v with failover cluster volumes on new SAN with new 2012 r2 hostnodes and 2012 r2 management server
2. Turn off the virtual machines on old 2008 r2 hyper-v hostnodes
3. Stop the VMMS service on the 2008 r2 hostnodes
4. copy the virtual machine files and folders over to the new failover cluster volumes
5. Import vm's into server 2012 r2 hyper-v.
Any feedback on the opertain I have in mind would be helpful.
Thank you,
RobHi Rob,
Yes , I agree with that "file copy " can achieve migration.
Also you can try "copy cluster wizard " :

Is there anything that needs to be done or considered when migrating from 2003 domain/forest level to 2008R2 with all DC's at 2008R2 with 2 other 2003 separate Domain incoming
and outgoing Trusts, one Trust that is a Forest Trust and the other is an External Trust? Is there any chance or risks that doing this upgrade will break either one of these Trust relationships? Some of the user accounts with SID history have been migrated
from both Domain Trusts to our domain. Any chance that this upgrade will break these relationships for users that are using SID history for access to folders and files in their old Domains? If so what can be done to protect these trusts and SID history, prior
to moving the Domain to 2008R2Hi,
Based on my knowledge,
the Upgrade of the function level do not affect the trust relationship.
Besides, before you upgrade the Functional Level,
verify that all DCs in the domain are, at a minimum, at the OS version to which you will raise the functional level.
Once the Functional Level has been upgraded, new DCs on running on downlevel versions of Windows Server cannot be added to the domain or forest.
For more information about function level, we can refer to following links:

Error:Package migration from version 8 to version 6 failed with error 0xC001700A
I was about to post a similar question where the package runs fine on VS2013 but errors when I run DTEXEC from the command prompt.
Error:
Code: 0xC0016020
Source: Package
Description: Package migration from version 8 to version 6 failed with error 0xC001700AHi TheDenver,
Based on the error message that “Package migration from version 8 to version 6 failed with error 0xC001700A ", we can infer that the underlying cause is that the current SSIS package is created in SSDT BI 2014 for Visual Studio 2013, while you are trying
to execute it with SQL Server 2012 DTEXEC. It seems that SQL Server 2014 Integration Services (SSIS) is installed on a machine that has SQL Server 2012 Integration Services (SSIS) installed, multiple versions of the dtexec utility are installed.
SSIS versions are not backwards compatible. SSDT BI for VS 2013 is used for SQL Server 2014, SSDT BI for VS 2012/SSDT 2010 is used for SQL Server 2012. Please notice that once a package is upgraded from SSIS 2012 package schema to SSIS 2014 package schema,
the package cannot be downgraded. So we cannot open or execute the SSIS 2014 packages with SSIS 2012 anymore.
To fix this, please ensure that you run the correct version of the utility, at the command prompt run the utility by entering the full path (<drive>:\Program Files\Microsoft SQL Server\120\DTS\Binn).
Reference:
dtexec Utility
Thanks,

One way would be to e-mail them from yourself to yourself. That would totally avoid the different ID issue.

Importing from a different character set
Oracle 8.1.7 / Windows NT
I'm trying to import a dump file which was created with character set WE8ISO8859P9. My database uses character set UTF8. Some of the records can't be inserted because of error "ORA-1401: Value too large for column". Is this because of the different character sets? If I switch my session to WE8ISO8859P9, imp says "character set conversion from x to y not supported."
How can I get these last records inserted? Here's an excerpt from the log:

Migrate from Lightroom 3 to Aperture 3 - Problems with DNG
Hello : )
I will migrate from Lightroom 3 to Aperture 3. I've tested Aperture for a while and I like it, but I have one problem. If I import DNG files, I lost all the settings I've made in Lightroom, except Metadata. Is there any way to import DNG files and get all the settings? If not I think a migration to Aperture will not be possible to me, because I've over 50.000 DNG files and I don't want to convert them to tiff or other formats and lost all the benefits of the RAW files.
Thanks

Migration from old to new iMac do you need to use set up on new or go straight to migration?
Just got a new iMac and going to migrate from my old 2008 iMac, info from Apple Support is a bit confusing but I want to know if it is best to use the "Set Up" on new iMac before migration or go straight into migration.
Also the support info says to connect both using ethernet as one option (which is my option) and connected to your network, how do you do this as there is only one ethernet port on each machine and if connected together it would not be possible to connect to a network, ie, the internet via my ISP. Suppot says no router etc needed.
Somewhat confused so if there is anyone out there who has done this I would appreciate their comments.
Thank you for any help forthcoming.

From Live Office XI R2 to Live Office XI 3.1
Planning to use Import Wizard Import SWF file from BOXIR to BOXI 3.1
Because of LIVE OFFICE is upgrading to BOXI 3.1, do i need to open Xcelsius 4.5 XLF(source file) into Xcelsius 2008 with SP3 and re-create SWF file & pubish into BOXI 3.1 ?
Without recreate new SWF[Xcelsius 2008], file previous[Xcelsius 4.5] version SWF file work in BOXI 3.1 or not ?I would recommend updating your 4.5 XLF in Xcelsius 2008 and repoint the data with the new Live Office connection and publish the SWF.

MD5 Migration issues using different character set
Hi,
DBname = test1 , db charcter set WE8ISO8859P1 ,os charcter set WE8ISO8859P1
DBname = test2 , db charcter set US7ASCII ,os charcter set UTF8
In both DB table1 having encrypted data using md5 encryption techniques . (dbms_obfuscation_toolkit.md5(input_string => v_input) )
Now i want to migrate data from test2 DB to test1 DB .How to migrate any one please help.
Thanks in advance
NaveenI'm not sure that I follow what you're suggesting but it sounds like you're on the right track.
I'm still not sure whether you need the MD5 hash to match data in the database or not. If you change the character set of the underlying data, the MD5 hash may change so just keeping the hash intact may not be sufficient.

You don't have to be connected to the same network in order to transfer files – your devices automatically set up a direct wireless connection for AirDrop.

Bought a new Mac Air this week. Tried to Migrate my files, etc from my old Mac Air running OS X 10.9 Mavericks. Discovered after repated attempts, that the new Mac Air has 10.8.4 Mountain Lion. Could this be why it will not work?
I would imagine so. I doubt the Migration Assistant is designed to go backwards.
