Where are the upgrade kits to 8.5.1 from prior to 8.5?

I reckon’ I’m supposed to download the smart upgrade kits from passport advantage. I can find these:

IBM Lotus Notes, Designer and Domino Admin Upgrade Kit 8.5 to 8.5.1 for

Windows 32 bit English(CZ5ZJEN)

IBM Lotus Notes Basic Configuration Upgrade Kit 8.5 to 8.5.1 for Windows

English(CZ5ZLEN)

IBM Lotus Notes Upgrade Kit 8.5 to 8.5.1 for Windows English(CZ5ZQEN)

underneath

IBM Lotus Notes Upgrade 8.5.1 for Windows English eAssembly(CR9YSEN)

Is there some way to upgrade people from 6 & 7 to 8.5.1?

Subject: There are none - use full kit

From the redbookhttp://www.redbooks.ibm.com/redpapers/pdfs/redp4180.pdf

 The Notes client full installation kit enables you to upgrade any client to a specific version.

For example, it can upgrade any release such as 6.0 to 7.0.1.

 The Upgrade kit is used to upgrade from any point release to another within its

codestream, such as any release of 6.5.x to 6.5.5.

 The Patch kit is used to upgrade from and to a specific point release. For example, a

specific patch kit is available to upgrade the client from 7.0 to 7.0.1.

Therefore, unless I am going from 8.5 to 8.5.1 I should use the full installation kit.

Confirmed this with a call to IBM.
