SSIS Package Upgrade

I have a SSIS Solution with 4 packages created in SSIS 2005. When I opened the solution in SSIS 2008, it went for SSIS Upgrade wizard. But the upgradation had failed. The error messages are shown as follows :

1. Error 0xc001405f:: Failed to decrypt an encrypted XML node because the password was not specified or not correct. Package load will attempt to continue without the encrypted information.

2. Error 0xc001f429:Package Upgrade: The loading of the package Package1.dtsx has failed

3. Error 0xc0016016: : Failed to decrypt protected XML node "DTS:Password" with error 0x8009000B "Key not valid for use in specified state.". You may not be authorized to access this information. This error occurs when there is a cryptographic error. Verify that the correct key is available.

What is the correct step for upgradation from 2005 to开发者_运维百科 2008 ?

SSIS packages developed in VS 2005 are not supported in VS 2008. VS 2008 need SSIS 2008. For more details check below link

Not sure if it helps, but if the packages were moved from a different machine, maybe you should check protection level at the original machine http://support.microsoft.com/default.aspx?scid=kb;en-us;904800
