WEBVTT 00:00.630 --> 00:07.050 Upgrading Safana now, I'm running version eight point two point three, a good way to verify that is 00:07.050 --> 00:12.330 to go to one of these pages, for example, configuration data sources there and at the bottom, it 00:12.330 --> 00:13.970 says eight point two point three. 00:13.980 --> 00:19.920 Now I haven't done anything with my server, so it's very safe to upgrade this to eight point 2.4 since 00:19.920 --> 00:22.050 I point to point four is now available now. 00:22.050 --> 00:27.630 Since I'm using the open source version, there is no guarantee of backwards compatibility, so this 00:27.630 --> 00:29.910 is something you do at your own risk. 00:29.970 --> 00:34.020 But right now, I don't have any data sources, so this is a completely safe thing to do. 00:34.050 --> 00:40.320 But do expect that if you do upgrade Gravano, some of your data sources or dashboards are no longer 00:40.320 --> 00:40.920 going to work. 00:40.920 --> 00:45.690 And that's just the reality of using Safana is that there are new versions of Safana every two weeks 00:45.690 --> 00:50.310 and something's going to break, so you just become good at it after a while figuring out how to fix 00:50.310 --> 00:51.660 up something that no longer works. 00:51.660 --> 00:54.810 If you do decide to upgrade your Farner, it's best to do it in small steps. 00:54.810 --> 00:58.020 Say, for example, I'm going to go to 8.2.2 for that. 00:58.020 --> 01:02.730 Why they were aren't going to be that many problems, as can be easy for me to refer to the documentation 01:02.730 --> 01:06.150 and find out what has changed since the previous version. 01:06.150 --> 01:10.830 But if you were to jump from version five to version eight, don't expect much to continue to work from 01:10.830 --> 01:14.780 that because Safana changes quite a lot over the different major versions there. 01:14.790 --> 01:16.680 So that's just the reality of using Gravano now. 01:16.680 --> 01:23.610 Also, since I'm using digital ocean before I do an upgrade, I can do a snapshot of the server, so 01:23.610 --> 01:28.200 I'm often a service admin page and digital version is an option here called snapshot, so I can take 01:28.200 --> 01:30.450 a live snapshot and that takes a minute or two. 01:30.450 --> 01:36.390 And then if I've broken my craft on a server, I can always restore from the life snapshot. 01:36.450 --> 01:40.640 Now I've done snapshots several times in the past and recovered from them, and they work very well. 01:40.650 --> 01:45.420 They just take a few minutes to create and to restore from whatever cloud platform you use will have 01:45.420 --> 01:48.640 a different version of backing up or taking snapshots. 01:48.690 --> 01:51.240 For me, this snapshot is by far the easiest way to do it. 01:51.330 --> 01:55.980 I'm not going to take a snapshot of Mega-fauna servers since it's just brand new anyway, and it's no 01:55.980 --> 01:57.660 risk whether I break it or not. 01:57.660 --> 02:04.380 And if I do break it by upgrading to a point 2.4, I can always reinstall eight point two point three 02:04.440 --> 02:04.830 anyway. 02:04.950 --> 02:08.320 The other consideration I have is when I install Safana. 02:08.400 --> 02:13.350 I select the Oasis version there and I used these instructions here. 02:13.440 --> 02:18.630 But actually they were written as I point two point three when I installed the upgraded version just 02:18.630 --> 02:20.040 shows the difference in numbers there. 02:20.070 --> 02:23.670 If you want to know what all the numbers are, it's just in this dropdown here. 02:23.700 --> 02:26.820 So eight point two point three they were the install instructions. 02:27.390 --> 02:30.900 Eight point two point four is my new install instructions. 02:30.900 --> 02:34.080 Now my server already has that, so I don't have to install that. 02:34.080 --> 02:35.880 So I'm just going to run that. 02:35.880 --> 02:39.740 I'm going to download the eight-point 2.4 and Debian package. 02:39.750 --> 02:40.550 So copy that. 02:40.560 --> 02:42.090 I'm on my server, right click. 02:42.090 --> 02:44.550 So I'm using get to download the package. 02:44.970 --> 02:46.530 100 per cent was very fast. 02:46.680 --> 02:50.130 Now I can install it by running the Debian Package Manager. 02:50.340 --> 02:54.850 Eight point 2.4 This technique I've shown you can be used to downgrade or upgrade. 02:54.950 --> 02:55.500 Doesn't matter. 02:55.530 --> 02:57.390 Just the numbers are the important things here. 02:57.720 --> 02:59.160 So right click Python. 02:59.160 --> 03:03.510 I mean the install, said Debian package manager on eight point 2.4 percent. 03:03.510 --> 03:03.750 So. 03:05.090 --> 03:09.150 So unpacking often a point to point for over eight point two points right there. 03:09.200 --> 03:13.610 OK, so it's doing now the whole process is still going to be happening in the background for about 03:13.610 --> 03:16.670 a minute if I go to this page and just refresh it. 03:17.510 --> 03:20.030 It now says eight point two point four at the bottom. 03:20.060 --> 03:24.710 Now this can take about a minute to happen, so it still says the audio version for you. 03:24.770 --> 03:26.000 Just give it a little more time. 03:26.030 --> 03:27.690 OK, so that's now a point to point. 03:27.710 --> 03:32.720 For now, that's pretty much it for upgrading and downgrading, but remember, it's open source, it's 03:32.720 --> 03:33.820 at your own risk. 03:33.830 --> 03:39.560 And to minimize the amount of work in fixing problems due to upgrading to one number at a time, eight 03:39.560 --> 03:46.070 point two point four means major minor patch either update each patch as they come through or update 03:46.070 --> 03:47.360 each minor version. 03:47.360 --> 03:49.760 So 8.3 is the next minor version. 03:49.760 --> 03:56.150 But the major bang version nine, I wouldn't recommend going straight from first night to version nine 03:56.150 --> 04:01.030 without at least going through some of the minor and patch versions beforehand. 04:01.050 --> 04:05.420 Remember to take a snapshot before you start the upgrade process if you think that's important enough 04:05.510 --> 04:09.060 using the options provided by your cloud platform. 04:09.080 --> 04:09.560 Excellent.
