Nope, went east for the first time in late '89.
Which isn't all that surprising, considering literally everyone who was young and that had the money and skills went west immediately after 1990. Some 2 million, about 15% of the East-German population - just in the period 1990 to 1993. Add at least a quarter million skilled "guest workers" who were sent "home" in the same period for the most part.
What was left was raped by the West German industry buying it up, and still hasn't pulled up to the West in any regard. A very big problem was also the sudden vast increase in wage costs for companies - wages were suddenly raised considerably through tariff agreements that went beyond establishing PPP. East Germany is estimated to have had a per capita income that was 40% of West Germany in 1990 - until 1998 this was raised to 80%. The second sector - Industry - in East Germany went bottom-up within months, and between 1989 and 1993 cut some 70% of its workforce. Only agriculture with a workforce cut of 80% was even worse off. The East German GDP shrunk by 35% between 1989 and 1991, and only reached 1989 levels again around 2002.
The whole thing is somewhat euphemistically summarized under "work efficiency adaption of East Germany".

As far as high-tech industry goes, a lot was simply cut in 1989/90. For example, Toshiba closed its plant in East Germany. RFT, the national East German electronics company conglomerate, nowadays still exists as a business association and consists among others of one of Germany's premier TV production companies (TechniSat), parts of Alcatel SEL (communication electronics), and a number of companies in broadband cable and other communications business venues. The East German aircraft industry was taken over immediately in 1989/90 by DASA/Airbus and nowadays belongs to EADS. The semiconductor industry (which delivered to the entire WarPac, pretty much anything that couldn't be imported) collapsed under international competition, and finally went bottom-up when a take-over deal with Intel fell through in 2003. The East-German computer industry was a bit more successful btw; a lot survived by itself for a number of years until taken over by Western companies such as Siemens and Samsung. VEB Carl Zeiss Jena doesn't really need an explanation. Probably the most successful East-German company after reunification. Same for Bergmann-Borsig, bought up by ABB and today still active under Alstom. East German motorcycles were so competitive and successful that they were already in GDR times exported to West Germany. The East German car industry - despite the ridicule for the Trabant and Wartburg models in the West - was taken down. AWE (Wartburg) was closed and replaced in the same town by a new Opel plant in 1992 (picking up the skilled workers), Sachsenring (Trabant) still exists as a component supplier after a series of corruption cases. The East-German agricultural machine industry (which directly competed with the Soviet one for notority) collapsed after it was split into dozens of companies, with the biggest one taken over by CASE International Harvester, and their plant surviving till 2004.
Precision Machinery, i.e. Niles Machine Tools, was taken over entirely - as they formed a holding post-reunification - by a West German competitor, and still exists today, albeit on a far smaller scale. Niles is a good example for the "drain" btw: the Kombinat had 22,000 employees in 1989 - and only 1,600 remaining by the end of 1990. Niles was the premier precision machinery producer in the entire WarPac since the 50s btw (way beyond any Soviet exports), although in the 80s exports to WarPac countries went down, with increased exports to the West compensating for that.
Their stuff was so good btw that i've worked at a major West German company in 2005 that was still equipped for certain machinery entirely with Niles products bought in the late 80s (and not as a cost-saving measure, but for the quality).
The rather huge shipbuilding industry in the GDR (8,400 workers in 1984), specialized in fishing vessels, collapsed when the (Russian) main private customer went bankrupt in 1993, with some 40 ships (standardized very large 7500t trawlers) still in the books to be built; the Volkswerft had produced over 350 large trawlers (above 80m), about 500 mid-sized trawlers (over 50m) and over 600 smaller cutters and loggers for the WarPac countries - with pretty consistent order books for the whole 40 years, gradually moving on to bigger ships over time.
Nowadays they produce Panamax container ships and offshore supply trawlers btw.
What really collapsed totally were steel works and the chemical industry, both using outdated machinery and production processes and way too much manpower.
