Dear BAS wizards,
I added cds 7 as dependency and cds-dk 7 as devdependency, but when I try to issue cds commands in a brand new BAS CAP workspace, I'm getting this error:
This application uses @sap/cds version >= 7, which is not compatible with the installed @sap/cds-dk version 6. Either update @sap/cds-dk to version 7 or downgrade @sap/cds to version 6 instead.
...
at build (/extbin/globals/pnpm/5/.pnpm/registry.npmjs.org+@sap+cds-dk@6.8.2/node_modules/@sap/cds-dk/bin/build/all.js:75:30)
This affects the built-in features as well

cds -v dumps the following
@sap/cds: 7.0.3 @sap/cds-compiler: 3.9.4 @sap/cds-dk: 6.8.2 @sap/cds-foss: 4.0.2 @sap/cds-mtx: -- missing -- @sap/cds-mtxs: 1.8.4 @sap/eslint-plugin-cds: 2.6.3 @sap/hana-client: 2.17.21 @sap/hdi-deploy: 4.7.1 @sap/xsenv: 3.4.0 MonitoringCockpitBS: 0.0.1 Node.js: v16.19.0 home: /extbin/globals/pnpm/5/.pnpm/registry.npmjs.org+@sap+cds@6.8.4/node_modules/@sap/cds
It seems 6.8.4 is used in BAS as external binary. Can I switch the version like like setting home to 7.0.2, which is also available in the
/extbin/globals/pnpm/5/.pnpm/
folder ?

With the June update CAP also recommends to use Node.js 18 because 16 is out of minatenance in 1 month. How can we use Node.js 18 in brand new BAS dev spaces, to follow SAP recommendadtions?
There are posts to do update by ourself or against to do it...
package-lock.json were deleted node modules wiped and completely renstalled in the projects.
Some references also checked about side-effects of release changes previously.
https://answers.sap.com/questions/13674288/cds-6-btp-cf-deployment.html
But none of them helped.
Workaround which makes cds serve working, but not cds build:
Moving cds-dk from devdependencies to dependencies in package.json helped, combined with npm rebuild command. But not sure we need cds-dk in production...
Also noticed after tegh above workaround that during cds serve the following that multiple cds versions detected:

As recommended in CAP June update I've added the new separate packages as dependency:
"@sap/cds": "^7",
"@sap/cds-common-content": "^1.2.0",
"@sap/cds-fiori": "^1.0.0",
"@sap/cds-hana": "^2.0.0",
"@sap/cds-foss": "^3.1",
Thank You
