sap best practice add-on's upgrade from ERP 6.0 EHP3 to EHP7

Dear All,

I need to upgrade our SAP BEST PRACTICE add-on's from EHP3 to EHP7.

While upgrading to ehp7 sum tool is asking me to take decision on following add-on's

Source Releases:

Target Releases: BPERP 617V6 & other add-on's.

Instead sum tool accepting bellow releases only.

I need to have SAP BEST PRACTICE ADD-ON IM&C in EHP7.

I tried to update both add-ons by placing files in EPS/in.

First I put BPERP617V, sum tool didn't find this package. Then I put BPERP05 603V8, it accepting this package.

SUM tool is taking BP-ERP05 603V7 to BP-ERP05 603V8(EHP3).  SUM Tool not accepting BPERP617V6 EHP7 PACKAGE.

How to upgrade the add-on's from BP-ERR05 to BPERP_617V6(which is applicable on ehp7) & BP-INSTASS to ehp7 release?

Do I need to undeploy them first and upgrade ehp7, after that deploy IM&C add-on?

                                                  or

Keep the version first and finish the ehp7 upgrade and then deploy on Existing ones?

Thanks & Regards
