What you have is an early release of SGD 4.61. You can probably safely upgrade from SGD 4.61.911 to SGD 4.63 (not 4.62) or 4.71 (just released last week) would be the best thing to do. Try it in the lab first before production. From 4.63 you can go to 5.0.
many thanks for the quick reply! It seems we'll go for 4.71 - at least for now: our main reason for the upgrade is that the certificates of the Java applets in Version 4.61 have expired and we expect that the applets in Version 4.71 have been signed recently so their certificates will be valid for a while. Is there any way to find out the period of validity of the applets' certificates *without* installing the package and trying the applet in the browser? Or does anyone have either 4.7, 4.71 or 5.0 installed and can tell me how long the Java applets' certificates will be valid? Wer are looking for a validtity period of at least two years (until 2015).
Thanks again & Kind regards,
