Germanic groups had abandoned (or died out in) most of Austria and all of East Germany between the Elbe and the Oder.
Then, Slavic groups occupied those deserted lands practically without mixing with anyone, because there were no people there.
At least, there is no archaeological and palynological (pollen diagrams) evidence of unbroken, continued habitation.
Pollen diagrams tell us that fields ceased to be farmed and wild forests started to grow over former settlement areas.
So by the 7th century, areas in question became fully Slavic-inhabited.
Only later, in the mid-12th century, a large-scale German immigration into Slavic-inhabited lands started (and continued over a few next centuries). Over the next centuries a linguistic shift gradually took place in some of those lands, from Slavic-speaking to German-speaking.
Slovenians and Czechs probably have some German and Celtic mix,
It is rather the other way around - West Slavs and South-Western Slavs are the most purely Slavic groups (from genetic point of view), while East Slavs and South-Eastern Slavs are more "racially" (so to speak) mixed with other, Non-Slavic, populations (such as Ugro-Finns / Uralics, native Siberians, a little bit of Mongols etc. in case of Russians, Turkic-speaking nomads etc. in case of Ukrainians, East Balts etc. in case of Belarusians and indigenous Southern European Balkan groups etc. in case of South-Eastern Slavs).
Slovenes and Czechs are in terms of ancestry more "original Slavic" than e.g. Bulgarians.
In genetic admixture analysis, Bulgarians can be modeled as a 50/50 mix of "Southerners" (ancient peoples who resembled genetically modern groups such as Sicilians, Cypriots or Armenians) and Northern Slavs or Lithuanians (the fact that Lithuanians can also "pass" as a "racial" proxy for Early Slavs only testifies to the truth already long known by linguists, which is that there had originally been a common Balto-Slavic "race" or community, which only later - relatively recently - split into Balts and Slavs).
There are words which carry the presage of defeat. Defence is such a word. What is the result of an even victorious defence? The next attempt of imposing it to that weaker, defender. The attacker, despite temporary setback, feels the master of situation.
